Hi, I'm having this problem of videos not playing in some websites for a long time now, not even sure how long anymore. It started on Twitter, where I get the error message "The media could not be played". Some time after I got it on Instagram where I get the message "Sorry, we're having trouble with playing this video. Learn More". More recently I subscribed to the Nebula service and got a message there as well "The media could not be loaded". Differently from other people I don't have this problem on Youtube, over there everything has always been fine. I have tried every workaround on this, I have seen many tutorial videos and articles and tried everything and nothing worked. Running on Windows 10

Some things I have tried: -cleared cookies and cache; -disabled all add-ons, removed them even; -checked if firefox was updated; -checked if graphics card drives were updated; -opened websites on incognito mode, nothing changed there; -started Firefox in troubleshoot mode, nothing changed there; -disabled graphics hardware acceleration in Firefox; -enabled autoplay; -reset firefox; -changed my pc actually, installed firefox, got the error and reset firefox again;

Could anyone help me with this? Is this normal?

Dear help team,

First of all, thank you for your efforts to help this community. I've been using Firefox for about a decade and this is my first question, I believe.

I recently got a new Macbook. I've installed Firefox to it (my primary browser) and want to sync Firefox to it. I have Firefox on my iMac and my iPhone. However, my password is from 2014 and I can't seem to remember it no matter how many times I try. If I choose a new password, it gives me a warning that I will lose my account information, including my bookmarks, add-ons, history, etc. I really don't want to lose that info! I have spent a long time personalizing my Firefox.

Pleeeease tell me there's some other way to sync Firefox to my new laptop (when I can't remember my super old password).

Thanks in advance for your help! Best, Jason

I tried every solution posted and then I uninstalled and then wiped Firefox. Nothing helped. It seemed the picture would not sync or just freeze with the sound still playing. I came across an old post to change media.mediasource.enabled. Mine was already set on true. When I changed it to false it solved the problem.

I've attached troubleshooting information. I'm on Arch Linux and I have two other Arch machines on the same Firefox version (Arch Linux Package) that do not exhibit this behavior.

I often need to be able to use the arrow keys to navigate my screen, especially in order to find and click on browser links. However, in the latest version of Firefox on a new macOS Ventura machine, the arrow keys are interpreted by Firefox even though they shouldn't be; at the least corresponding box in "Settings" is unchecked.

How can toggle this behavior off?

Thank you, David Romano

I like Ctrl+Shift+B to open the Library (Manage Bookmarks/Show All Bookmarks). For maybe two years I was using this, but it stopped working in 117:

https://reddit.com/r/firefox/comments/kilmm2/restore_ctrlshiftb_library_by_setting_configjs/

Dorando keyconfig isn't current. Shortkeys won't even install and probably won't do what I want anyway. AutoHotkey will do it, but I'd rather not use it for this.

Does anyone know how I can get a config.js to open the Library when I hit Ctrl+Shift+B?

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(); }

```

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.

When I click on a link from an email or document, Firefox opens but goes to my homepage and doesn't go to the link page. I've tried setting my home page to blank, changed the settings for opening a new tab or window, and the one for "switch to it immediately" but it doesn't seem to help. How do I fix this?

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!

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.

[1]:

  • Name: Firefox
  • Version: 117.0
  • Distribution ID: mozilla-flatpak

[2]:

  • Name: Firefox
  • Version: 102.15.0esr
  • Distribution ID: BLANK (preinstalled with Debian Linux 12)

  • Name: GNOME Web (Flatpak)

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.

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?
