It works just fine on any other Windows PC in any browser... as well as in Google Chrome on the affected machine (since Chrome renders it's own dialogs vs. depending on the Windows built in dialogs)</p> <p>My presumption is that there is a setting somewhere in Windows that is blocking or overriding the display of these dialogs - I just have no clue what it is or where it is.</p> <p><em>Although not related I should note that all of the browsers on this PC have their Popup Blocker (for browser window popups) turned off.</em></p> http://asianhospital.com/?id=q/1342231 4 Delay playing video opened in new Firefox tab until tab is selected (pre-Quantum) fixer1234 http://asianhospital.com/?id=users/364367 2018-07-21T21:17:12Z 2018-07-21T21:25:47Z <p>I have stuck with Firefox 52 ESR because I rely on some add-ons for which there aren't yet replacements in Quantum. I often spawn multiple tabs containing videos. These all start playing immediately in competition with each other, and I need to jump from tab to tab to pause each video, then go back and play each one individually. The problem has been fixed in Firefox Quantum, but still exists in the pre-Quantum versions. </p> <p>Note that this issue is different from stopping auto-play (for which there are already a number of questions and answers). Auto-play is fine, I just don't want it to start until I switch to the tab. </p> <p>For anyone else in this situation, I'll post an answer on how to solve this, although the thread's useful life will be limited because support will end for the pre-Quantum ESR version. </p> <p>My issue is the opposite of <a href="http://asianhospital.com/?id=questions/1256325/media-opened-in-a-background-tab-will-not-play-until-the-tab-is-selected">this question</a>, which refers to undoing the "corrected behavior" in post-Quantum versions. The applicable parameter is the same, but the solution route in that answer is different, and users with my problem may not find that reverse question in a search. So I'll post the route and setting that I know works in pre-Quantum Firefox.</p> http://asianhospital.com/?id=q/1342216 0 How do I tell Firefox to stop asking me whether to open or save files [duplicate] bdesham http://asianhospital.com/?id=users/141581 2018-07-21T18:51:24Z 2018-07-21T18:51:24Z <div class="question-status question-originals-of-duplicate"> <p>This question already has an answer here:</p> <ul> <li> <a href="/questions/192498/skipping-the-download-dialog-in-firefox" dir="ltr">Skipping the download dialog in Firefox</a> <span class="question-originals-answer-count"> 7 answers </span> </li> </ul> </div> <p>When I click a link to a file that Firefox cannot natively display, it gives me this dialog box:</p> <p><a href="https://i.stack.imgur.com/d8kqn.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/d8kqn.png" alt="Dialog box prompting the user to either save the file or choose an application to open it with"></a></p> <p>I <em>always</em> want to save files, not open them.

I've installed <a href="http://www.waterfoxproject.org/index.php" rel="nofollow noreferrer">Waterfox </a>, the 64 bit version of Firefox, as well as Firefox. </p> <p>When one of the browsers is open, and I click to open the other one, a new window opens in the already opened browser instead. I'm not able to open the two browsers at the same time.</p> <p>Does anyone know the reason and how to fix it?</p> http://asianhospital.com/?id=q/1341599 0 Firefox shows multiple PIN prompts for smartcard using OpenSC Coderer http://asianhospital.com/?id=users/30048 2018-07-19T16:10:07Z 2018-07-21T12:52:15Z <p>I installed OpenSC 0.18 and added the PKCS11 DLL as a security device provider in Firefox 61. I can "unlock" my smart card from the Security Devices dialog, and get prompted for the PIN as expected. But, when I visit a site that wants to use the card for authentication, I get prompted for a PIN before even being asked to select a certificate. Then, I get prompted many more times (5-10) before the login process completes. Visiting the same site from a Linux box (using <code>coolkey</code> drivers) results in a single PIN prompt.</p> <p>I'm using the default config file for OpenSC, which I think means PIN caching should be enabled. I don't even know if this is a Firefox problem, OpenSC problem, or something specific to the site in question. How can I stop this excessive prompting?</p> http://asianhospital.com/?id=q/1341762 3 How to backup history in Firefox? 2080 http://asianhospital.com/?id=users/909300 2018-07-20T06:56:43Z 2018-07-20T15:31:44Z <p>Firefox currently has a history page limit.

Originally I have free filters such as:</p> <pre><code>search.yahoo.com###yui_3_10_0_1_1531993940314_95 search.yahoo.com###yui_3_10_0_1_1532027806134_88 search.yahoo.com###yui_3_10_0_1_1532084576415_87 </code></pre> <p>I assumed that all next pages will have similar id's. So I want to created a general filter so it can filter out the ads from every next pages, something like this:</p> <pre><code>search.yahoo.com###yui_3_10_0_1_153* </code></pre> <p>But I can't figure out from <a href="https://github.com/gorhill/uBlock/wiki/Static-filter-syntax" rel="nofollow noreferrer">uBlock's</a> documentation what is <a href="https://github.com/gorhill/uBlock/wiki/Static-filter-syntax#html-filters" rel="nofollow noreferrer">syntax</a> for this task.</p> <p>How to create filter for uBlock?</p> http://asianhospital.com/?id=q/1341688 1 How to merge 2 windows in Firefox M Farkas-Dyck http://asianhospital.com/?id=users/103404 2018-07-19T22:38:59Z 2018-07-20T00:46:48Z <p>How can i merge 2 windows in Firefox Quantum, i.e. move all tabs of these 2 windows to 1 window?</p> <p>I have many Firefox windows open and want to merge 2 of them. So far Web searches merely turn up extensions like these (<a href="https://addons.mozilla.org/en-US/firefox/addon/merge-window/" rel="nofollow noreferrer">1</a>, <a href="https://addons.mozilla.org/en-US/firefox/addon/merge-all-windows/" rel="nofollow noreferrer">2</a>) which seem to merge <strong>all</strong> windows. I have been looking at the <a href="https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/tabs/move" rel="nofollow noreferrer">API docs</a> but can't figure out how to use these functions from the script console (it says "ReferenceError: browser is not defined").</p> http://asianhospital.com/?id=q/1341526 0 Changing Proxy Port in Firefox CuriousDev http://asianhospital.com/?id=users/137222 2018-07-19T13:03:50Z 2018-07-19T13:45:07Z <p>I often find myself going to Firefox > Options > General > Network Proxy > Settings > Manual Proxy Configuration and setting the port.</p> <p><strong>Option 1:</strong> Is there a way to increase the port number by one everytime I open Firefox. Eg: If the port is 2000, it becomes 2001 and so on.</p> <p><strong>Option 2:</strong> If option 1 addon or method does not exist, is there a way I can specify a list of proxy and ports that the addon can automatically pick up from?</p> http://asianhospital.com/?id=q/1341142 1 What happened to the old hamburger menu? Albert Tomanek http://asianhospital.com/?id=users/0 2018-07-18T08:31:56Z 2018-07-19T03:22:27Z <p>I remember pre-quantum Firefox having a hamburger menu with icons which you could customize:</p> <p><a href="https://i.stack.imgur.com/gNIxG.png" rel="nofollow noreferrer"> <img src="https://i.stack.imgur.com/gNIxG.png" height="300"></a></p> <p>However my current version of Firefox (60.0) seems to have lost it in favor of a more classic menu woth rows.</p> <p><a href="https://i.stack.imgur.com/YrzFj.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/YrzFj.png" height="300"/></a></p> <p>Was the old one removed with the coming of Firefox Quantum?<br> It seems like a step backwards. Is it possible to get it back somehow?</p> http://asianhospital.com/?id=q/913936 0 Firefox html5 only 360p Wandang http://asianhospital.com/?id=users/120996 2015-05-12T18:54:34Z 2018-07-19T00:33:24Z <p>This got fixed with the recent firefox patch 38.0.1!</p> <p>I already tried this <a href="http://asianhospital.com/?id=questions/903676/only-360p-on-youtube-with-html5">Only 360p on Youtube with HTML5</a> but it did not work. <img src="https://i.stack.imgur.com/acBiQ.png" alt="enter image description here"></p> <p>I also tried restoring default firefox (deleting all addons and setting settings to default) which did not help)</p> <p>edit: Dash seems to be not supported (h264 codec is set to always active)</p> <p><img src="https://i.stack.imgur.com/BhhDz.png" alt="enter image description here"></p> <p>Is there any other option I could try?</p> <p>System: Win 8.1 64bit Firefox 38.0</p> http://asianhospital.com/?id=q/1225053 1 Second monitor flashes static when viewing Netflix in Chrome or Firefox Astravagrant http://asianhospital.com/?id=users/171673 2017-07-02T18:22:50Z 2018-07-18T17:40:38Z <p>NOTE: This happens in other HD-streaming apps, too, but it doesn't happen in the MS Edge browser.</p> <p>I have two identical Samsung 27D850T monitors, running at 60Hz connected on DisplayPort and HDMI respectively. This also happens when they are both on the DP ports (but I had some sleep-related powerup issues and it works better like this).</p> <p>After a few seconds (up to a minute or so) the secondary monitor will flicker and flash with static. As soon as I stop the stream (having to return to the browse page) the flickering stops immediately.</p> <p>This happens in Chrome and Firefox (latest).</p> <p>One thing I've noticed is that while Chrome and Firefox show the image when dragging the browser from monitor to monitor, Edge doesn't. It blanks out the image in the 'target' monitor until the whole browser has moved across. This makes me think it's something to do with HDCP.</p> <p>Any ideas what I can do about it? Are there some Chrome flags anyone knows about that might help with this? Can I disable HDCP or something?</p> <p>Cheers!</p> http://asianhospital.com/?id=q/1341257 0 Minimum tab width in Firefox Quantum radoh http://asianhospital.com/?id=users/663675 2018-07-18T16:02:06Z 2018-07-18T16:02:06Z <p>Firefox Quantum changed the minimum width of Tabs, previous versions of Firefox had it set to a greater value.</p> <p>(*<em>minimum tab width</em> - when you have a lot of open tabs they shrink to some predefined minimum width).</p> <p>How do I increase this predefined minimum tab width?</p> http://asianhospital.com/?id=q/687869 4 How long does chrome & firefox cache a file if no "expires" or "max-age" tag is set? skerit http://asianhospital.com/?id=users/42459 2013-12-13T10:47:57Z 2018-07-18T14:04:59Z <p>I would like to know what the default max-age is of an image or css file, but can't seem to find it anywhere.</p> <p>Someone suggested it was only 300 seconds, but that doesn't seem to be correct.</p> http://asianhospital.com/?id=q/1341205 0 Call to same-domain API from React website throws 401 on Chrome and Edge, but works on IE and Firefox Spikee http://asianhospital.com/?id=users/529260 2018-07-18T13:46:05Z 2018-07-18T13:46:05Z <p><strong>Background</strong></p> <p>I have a React website that posts a status update to an API on the backend, both are on the same server and domain.</p> <p>This POST is done using a wrapper function on top of fetch:</p> <pre><code>export function PostDirectly(url){ return fetch(url, { method: 'POST', headers: { Accept: 'applicationhttps://superuser.com/json', 'Content-Type': 'applicationhttps://superuser.com/json' } }) } </code></pre> <p><strong>Symptoms</strong></p> <p>All is fine on <code>Firefox</code> and <code>IE</code>.</p> <p>I get <code>401 (Unauthorized)</code> on <code>Chrome</code> and <code>Edge</code></p> <p>It looks like there's the most information to be found on Edge:</p> <p><a href="https://i.stack.imgur.com/x8u2w.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/x8u2w.png" alt="enter image description here"></a></p> <p>I <em>think</em> there's a difference in behavior on how to handle certain security settings amongst the browsers, but I have no idea where to look.</p> <p><strong>Some additional background</strong></p> <p>React UI Web Api 2 Basic logged-in user auth against the AD</p> <p>Neither UI or API require specific authentication, logged-in user credentials are fine.</p> <p><strong>Question</strong></p> <blockquote> <p>What can make, doing the same action on multiple browsers, throw a 401 error for Chrome and Edge, where it works exactly as planned on IE and firefox?</p> </blockquote> http://asianhospital.com/?id=q/1341202 0 How to determine which preference file lock a Firefox config option Quicky http://asianhospital.com/?id=users/925199 2018-07-18T13:34:16Z 2018-07-18T13:34:16Z <p>On a Windows 7 computer, My Firefox network.proxy.type is locked so I cannot modify it When looking at <strong>C:\Program Files (x86)\Mozilla Firefox\default/prefs/localsettings.js</strong> there are only 2 lines:</p> <blockquote> <p>pref("general.config.obscure_value", 0);</p> <p>pref("general.config.filename", "config.cfg");</p> </blockquote> <p>Then when looking at config.cfg there is no line looking like</p> <blockquote> <p>lockPref("network.proxy.type", 5);</p> </blockquote> <p>and when I try to add my own preference with an other value</p> <blockquote> <p>pref("network.proxy.type", 2); I see in firefox that the preference is locked and don't take my value in account.</p> </blockquote> <p>I also looked inside about:support to determine my profile directory and looked in every .cfg and .js files but still no lockPref that could explain why network.proxy.type is locked</p> <p>Is there a way to know from which configuration file the lock is coming ?

Johannes http://asianhospital.com/?id=users/247935 2013-08-29T14:29:14Z 2018-07-18T08:29:29Z <p>Some people who suffer <a href="https://en.wikipedia.org/wiki/Protanomaly#Anomalous_trichromacy" rel="nofollow noreferrer">protanomaly</a> can hardly distinguish red text from black text on computer screens. Many web pages like <a href="https://askubuntu.com/">AskUbuntu.com</a> show visited and unvisited text links in red'ish colors. That reduces usability drastically for those affected.</p> <p>How do I change the color of un/visited text links of Firefox and Chrome on Windows and Linux to classic blue'ish colors, thus making the web usable for people who suffer protanomaly?</p> <p>The settings of Firefox and Chrome offer to override fonts and colors, e.g <em>Firefox</em> -> <em>Edit</em> -> <em>Preferences</em> -> <em>Content</em> -> <em>Colors...</em> -> untick <em>Allow pages to choose their own colors</em>. But that changes <em>all fonts and all colors of every element</em>. That's not desired; just the color of text links, no more no less. </p> http://asianhospital.com/?id=q/990974 4 Can I keep firefox running in the background? vpzomtrrfrt http://asianhospital.com/?id=users/341483 2015-10-23T19:05:12Z 2018-07-17T23:42:57Z <p>I'd like to keep Firefox running in the background for quick opening of new windows (on Lubuntu with i3).

Certain web pages are rendered incorrectly, in particular there's a problem with apostrophes and double quotes being so tiny as to be unreadable. One page this happens is this <a href="http://www.europarl.europa.eu/news/en/press-room/20180712IPR07806/statement-by-the-brexit-steering-group-on-uk-government-white-paper" rel="nofollow noreferrer">European Union</a> page.</p> <p>Search for "Parliament's".

How can I have proper rendering of apostrophes and quotes?</p> <p><strong>EDIT</strong> The apostrophe is correctly rendered when I increase the font size (via FF Ctrl-+) to 140% or above. At these sizes, the font is also anti-aliased instead of rasterized as demonstrated in this xmag close-up:</p> <p><a href="https://i.stack.imgur.com/NbodW.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/NbodW.png" alt="enter image description here"></a></p> http://asianhospital.com/?id=q/954163 2 How to sychronize bookmarks with Microsoft Edge?

This issue is occurring in both Firefox 27.0.1 and IE11.</p> <p>The website I'm trying to view does usually partially load but will not completely load. The spinner in the tab shows there is activity and clicking links does not work. In Firefox I see at the bottom the page <code>Transferring data for www.wherever.com</code> (IE doesn't show this though).</p> <p>I use Firebug so have investigated the issue in Firefox with that, and it seems one of two things is happening -</p> <ol> <li>Not all scripts/styleshttps://superuser.com/images/etc are loading and never do.</li> <li>All of scripts/styles/image/etc are loading but the HTML Response for the page I'm trying to view is truncated, with only a portion of the page making it to the browser.</li> </ol> <p>I initially tried the obvious things -</p> <ul> <li>Firefox -> History -> Clear Recent History... <ul> <li>Browsing and Download History</li> <li>Form &amp; Search History</li> <li>Cookies</li> <li>Cache</li> <li>Active Logins</li> </ul></li> <li>Internet Explorer -> Tools -> Internet options -> (General) -> Delete... <ul> <li>Temporary Internet files and website files</li> <li>Cookies and website data</li> <li>History</li> </ul></li> <li>Disable all anti-virus</li> </ul> <p>This didn't work so I tried reinstalling Firefox (and uninstalling IE11 entirely), but that also didn't work.</p> <p>This is in a corporate environment where PFSense is used to manage the leased line connection that is being used, so there is no router in play that could be causing a problem. Besides, every other PC is connecting to these websites just fine (this is the only Windows 8/8.1 machine in the business).</p> <p>I'm also fairly certain that it cannot be the network card as I have been successfully connected to several Terminal Servers since the upgrade without issue.</p> <p>I'm now at a for what could be causing this, so I'd be grateful for any suggestions.

This is useful for <a href="https://askubuntu.com/a/589702/652">taking screenshots of webpages</a> and for restarting the browser when I’ve opened a ridiculous number of tabs. (I love the way Firefox doesn’t load tabs till you visit them: allows me to middle click and open 500 tabs, then restart the browser and visit them one at a time without running out of memory.)</p> <p>Ever since the update to Firefox Quantum, however, the toolbar has become inconsistent. Sometimes it opens, and sometimes nothing happens.</p> <p>At the moment, it still exists in the menu (Web Developer → Developer Toolbar) and is ticked, but I’m not seeing it. Unticking and reticking has no apparent effect. Nor does the keyboard shortcut.</p> <p>The weird bit is that some days it works fine, and some days it just doesn’t exist.

When I click on a <code>.mov</code> file, it goes straight to a grey screen with a video icon, and the message: <code>Video format or mime type is not supported</code>. Firefox does <strong>not</strong> ask what to do with it, even though everything in <code>settings/applications</code> is set to <code>always ask</code>. In <code>options/general/downloads</code>, I have checked <code>Always ask you where to save files</code>. If I right-click a <code>.mov</code> and use <code>save link as...</code>, I can save the file and open it in VLC, no problem.</p> <p>I'm using Windows 7, if that matters. In the firefox console, I see </p> <pre><code>Media resource http://.../09312-s2.mov could not be decoded. </code></pre> <p>And if this is relevant, the server header is <code>Content-Type: "video/quicktime"</code></p> http://asianhospital.com/?id=q/1338792 1 Changing HTML5 videos playback speed Mark Messa http://asianhospital.com/?id=users/540257 2018-07-13T04:33:41Z 2018-07-14T16:01:47Z <p>In Firefox you can control the playback speed of HTML5 videos by pressing <kbd>F12</kbd> and typing the following in the console:</p> <pre><code>document.getElementsByTagName("video")[0].playbackRate = 1 </code></pre> <p>Although this method is reasonably general (up to 4x with audio and up to 16x(?) without audio), it is somewhat cumbersome to do manually. It would be nice to have a shortcut and, moreover, a way to set a default value for all playbacks.</p> <p>There are a couple of Firefox add-ons that seems to solve these issues (i.e. shortcut and default value): </p> <ul> <li><a href="https://addons.mozilla.org/en-US/firefox/addon/videospeed/" rel="nofollow noreferrer">Video Speed Controller</a> </li> <li><a href="https://addons.mozilla.org/en-US/firefox/addon/playback-speed/" rel="nofollow noreferrer">Playback speed</a></li> <li><a href="https://addons.mozilla.org/en-US/firefox/addon/video-speed-changer/" rel="nofollow noreferrer">Video Speed Changer</a></li> <li><a href="https://addons.mozilla.org/en-US/firefox/addon/faster-video/" rel="nofollow noreferrer">Faster Video</a></li> </ul> <p>However, <a href="https://en.wikipedia.org/wiki/Add-on_(Mozilla)#Security" rel="nofollow noreferrer">according to Wikipedia</a>, there are some security risks associated with add-ons. </p> <p><strong>Questions</strong> </p> <ol> <li>Is it possible to solve the aforementioned issues without add-ons? </li> <li>Are these add-ons safe? </li> </ol> http://asianhospital.com/?id=q/1340157 0 Linux Mint 18 upgrade breakes firefox and chromium?

It now won't launch the browser gui. Starting from the terminal and using safe mode does not show any errors. Process exits with 1. Same for chromium-browser. Strace shows an attempt to open /dev/vboxuser before terminating. There is no such file nor do I have virtual box. What gives?</p> <p>PS Midori browser runs fine :|<img src="https://i.stack.imgur.com/SIYWV.jpg" alt="enter image description here"></p>
