After the latest update (117.0 64-bit) I now do not see the '+' sign in the tab bar. I have 40 tabs open (please, no negativity - it's always worked for me), but if I close all of the tabs it reappears. Re-open the original 42 tabs and it's gone again. Close them and it reappears, etc. Now for the fun bit: starting from scratch with a new window - the '+' is there, but open 20 more tabs and it goes.

Firefox just turns into a black screen and becomes unusable. It has been happening for a long time now and i have checked RAM and CPU usage and they are all fine, as I explored potential causes.

I will be using firefox and it just turns all black on all screens and is completely unusable. To use it again I have to force close all windows and reopen it and it works again.

This is a frequent issue that I have seen

When i go to open a PDF file with Firefox, the text renders incorrectly (see image) for most PDF files, but not all (i'm not sure why. And this only happens with the Flatpak version of Firefox [1]. It doesn't happen with Firefox ESR (DEB version from my distribution) [2] and it doesn't happen if i view the same PDF file with pdf.js in a non-Firefox Flatpak app (GNOME Web) [3].

I've tried reinstalling and tried starting in troubleshoot mode, but neither seemed to fix the issue.

I don't know why, but since today firefox keeps reloading all my tabs I have open every couple of minutes. It happens on both my desktop and laptop and its getting annoying. I also disabled the auto refresh in config, along with clearing the cache. I uninstall the plugins that I installed last week, and still happens.

This morning i restarted firefox and it only opened 3 of the 4 windows i closed yesterday. I've just read about the limit of 3 windows reopened after closing, but now i can't restore the 4th one (it was the manin window with many tabs opened). In history i can't click on "Recently closed windows" and ctrl-shift-n doesn't work. I made a backup of my profile outside of the usual firefox folder. Is there something i can do to restore the 4th windows? I don't mind losing the other windows, but i need to recover the main one. I also tried this tool https://www.jeffersonscher.com/ffu/scrounger.html but it doesn't seem to work with the files inside startupCache.

The excellent answer here no longer works in Firefox 117.0 on MacOS. Unfortunately, that post is archived, so I cannot post an updated solution there. I would greatly appreciate if a moderator could add this post in the linked article, or at least link from there over to here.

For Firefox 117, the code needs to be modified slightly (two lines at the top need to be removed): ```

  //
  function ConfigJS() { Services.obs.addObserver(this, 'chrome-document-global-created', false); }
  ConfigJS.prototype = {
   observe: function (aSubject) { aSubject.addEventListener('DOMContentLoaded', this, {once: true}); },
   handleEvent: function (aEvent) {
     let document = aEvent.originalTarget; let window = document.defaultView; let location = window.location;
     if (/^(chrome:(?!\/\/(global\/content\/commonDialog|browser\/content\/webext-panels)\.x?html)|about:(?!blank))/i.test(location.href)) {
       if (window._gBrowser) {
         let keys = ["key_find", "key_findAgain", "key_findPrevious", "key_gotoHistory", "addBookmarkAsKb", "bookmarkAllTabsKb", "showAllHistoryKb", "manBookmarkKb", "viewBookmarksToolbarKb", "key_savePage", "key_search", "key_search2", "focusURLBar", "focusURLBar2", "key_openDownloads", "openFileKb", "key_reload_skip_cache", "key_viewSource", "key_viewInfo", "key_privatebrowsing", "key_quitApplication", "context-bookmarklink"];
         for (var i=0; i < keys.length; i++) {
            let keyCommand = window.document.getElementById(keys[i]);
            if (keyCommand != undefined) { 
               keyCommand.removeAttribute("command"); 
               keyCommand.removeAttribute("key"); 
               keyCommand.removeAttribute("modifiers"); 
               keyCommand.removeAttribute("oncommand"); 
               keyCommand.removeAttribute("data-l10n-id"); 
            }
         }
       }
     }
   }
  };
  if (!Services.appinfo.inSafeMode) { new ConfigJS(); }

```

I am using an extension that automatically deletes cookies on Firefox startup. But when I start firefox, I am getting sites listed showing they have one or more cookies but are using no storage. Another Firefox extension indicates there are no cookies from the sites that "Manage Cookies and Site Data" says do have cookies.

Is this a bug in Firefox, a bug in the extension, or a misunderstanding on my part?

Hiya. I usually have a fairly large number of tabs open on the browser. I use the Panorama View add-on for tab management. Usually this means that on any given container I have about 10-20 tabs open for a total of some 300 odd tabs. The nice thing is that Firefox doesn't usually load all my tabs so this works out for me. Recently however something weird's been going on and Firefox just refreshed ALL my tabs across all the containers. This kills my performance completely, especially given a fair number of tabs are just random youtube links. When all my tabs are open Firefox eats up like 25 GB of RAM, which is understandably not great.

I tried refreshing Firefox to no avail. Is there any way to stop this constant loading of all tabs?

Using Firefox 117.0 (64 bit) with Windows 10 Pro 22H2, I have www.google.co.uk set as the home page. Whenever I use the homepage search box to enter a search term, Firefox stalls for about 10 seconds before showing the search results. Selecting any search results opens the relevant page straightaway. Subsequent new searches using either the search box at the top of the results page or the home page again also has the 10 second delay. Using the search box in the Menu Bar does not have this delay - the results are shown straightaway. This has been happening for the past two weeks or so and using the previous version of Firefox. I've been using Firefox for many years and have never had this problem. Chrome works fine. I've tried all the "solutions" found on the internet, refreshed Firefow, tried a new profile, troubleshoot mode, etc, without any change. Also, within the past 24 hours, I can no longer open www.screwfix.com - with www.screwfix.com in the address bar, I get a completely white page without any error message. Screwfix opens fine with Chrome on this machine and with Firefox on Android tablet and phone. Please can you help with this. I'm in the UK. Thanks

All images, webm, gif etc. are loading, seemingly, exactly 20% upscaled compared to the real resolution of the media. I'm using a 4k TV (S95B), but I have desktop scaling at 100%, and browser scaling at 100%. I don't believe it's a GPU or OS system wide type setting because windows photo viewer gets pictures right. I'm using ShareX to measure the pixels of pictures. I can even load a local picture in a tab, and it will be upscaled beyond its native resolution. I have no idea why. I've tried a bunch of things, like setting layout.css.devPixelsPerPx to 1.0, which did nothing. I've reset Firefox to no avail, and I have noticed that Chrome is doing the same thing, which would usually indicate it could be the OS or GPU driver, but again, other apps load images perfectly normally. Do apps have categories on Windows now, where something like a "browser" can be told to treat media files differently than other media handling categories? I'm really lost at this point, nothing seems to work.

Client type : desktop Firefox Developer Edition Client version : 117.0b9 (64bits) Client language : Korean OS type : Windows 10 Home 22H2 OS version : 19045.3208


Steps to reproduce : 1. Run Firefox Developer Editon. 2. Try searching using the navigation bar on the home screen. 3. Enjoy that nothing happens.

Expected Result : Happy life at Firefox

Actual Result: Tedious LOADING


I've been using Firefox Developer Edition for the past two years without problems. From some point on(about 1 week ago), All browser's search functions suddenly don't work. Navigation bar? Not work. Searchig from Bookmark? Not work. Do not use google? Not work even with duckduckgo. with out DNS? Not work even with 142.250.206.206. There is only one website that i can access with Firefox Developer Edition. It is Mozilla's official website At this moments, I curious that "why isnt work>?" So i used Developer tools, And then I found something amazing. There was no request or response on the Network tab! (Of course, I pressed Ctrl + R) And then, on second thought, I found that the JS function that should have been small in the lower left of the browser screen was not displayed. Finally, I thought, hmm... My Firefox is broken! So i found the FireFox, and then i uninstall it, and reinstall it! All the External Plugin works, OK then What if FireFox????? Unfortunately, Firefox Developer Edition's problem remained the same. I'm sorry that i couldn't even give you a possible cause of the problem. But i SUFFER for a week! Please resolve the issue.....

Have had this problem for a couple of years now, across dozens of Firefox updates. Decided to finally make a post since have not been able to find anything online.

Normally not too much of an issue as I can edit on a different computer through Firefox Sync (or through the Bookmarks manager), just posting to see if anyone else has seen this before.

If I open a Bookmarks Toolbar folder, then right-click a bookmark to edit it, the contextual menu appears behind the open folder dropdown menu.

Issue persists even if I reset Firefox, or even completely uninstall / remove ALL its bits and pieces, reboot, and do a clean install.

Since I am on a Mac, I use the AppCleaner app from FreeMacSoft to completely remove an app.

This happens only on one of my two Macs. Have never seen this behavior on any other Mac (I work on dozens for work). Both my Macs also have Win 10 installs through BootCamp and those two also behave normally. I use Firefox Sync across 4 Firefox installs (2 Mac OS and 2 Win 10), an iPhone, and an iPad.

Screenshot enclosed below. Feel free to ask for any other info you may need. I recognize this may not be a Firefox issue. There seems to be a funky interaction between my install of Mac OS and Firefox. This occurs only with Firefox. All other apps exhibit normal menu behaviors.

Tech details: Firefox 117.0 Mac OS Catalina 10.15.7 running on mid 2012 15" MacBook Pro with 1 TB SSD and 16 GB RAM

Many Thanks!

Hi all. I've been using Firefox for years on my Mac. It's my browser of choice.

A couple of days ago, my Mac installed an OS update (v13.5.2). After the reboot, I opened Firefox and discovered that it, too, had installed an update (v117.0). But when I got into Gmail and tried to turn on desktop notifications, it said this:

Note: Notifications have been disabled in this browser.

And it's right--no other sites are sending me their usual notifications, either.

My problem is, I can't figure out why notifications are disabled in Firefox suddenly. I didn't disable them. I've tried clicking the lock on gmail's site and setting its permissions to allow notifications, but they aren't coming. I've checked my Mac's preferences, and Firefox has notifications enabled there, as usual. Gmail works fine on Chrome--notifications are working. I've tried reinstalling Firefox--no change. I've tried running Firefox in troubleshooting mode--no joy. Other sites aren't even asking for permission to send notifications. Like Gmail, they appear to believe notifications are disabled in the browser.

I've searched the web for solutions, but I can't find one that tells me where the enable/disable switch is. Can some kind soul please help me out here?

Thank you SO MUCH in advance!!
