System Info: 1. Windows 10 Home 22H2 (as of writing) 2. Firefox 118.0.2 (as of writing)

I'm trying to make the simple change of moving the location of the 'find in page' bar from the bottom to the top and I recently discovered that using userChrome.css was the way to do it. I followed this tutorial in the following link, https://www.userchrome.org/how-create-userchrome-css.html, making sure to put the "chrome" folder in the right location C:\Users\myName\AppData\Roaming\Mozilla\Firefox\Profiles\sfytm5xk.default-release, switching the toolkit.legacyUserProfileCustomizations.stylesheets to true, entering the code snippet into the userChrome.css using VSCode, and restarting the browser for the changes to take effect.

After the first restart, I found that the 'find in page' bar was still at the bottom and nothing had changed. I restarted the browser about 10 more times and nothing changed still. I looked through the Mozilla Support forums, r/FirefoxCSS and r/Firefox subreddits for an answer and came across a few posts with similar problems, tried their recommended solutions such as downloading the userChrome.css file from the website tutorial, double-checking that File Explorer would show file extensions when creating or renaming files, or even restarting my computer and yet none have worked.

I have no idea what's wrong so feel free to share what you think the problem might be and possible solutions in the replies.

Hello. Can someone please explain why Facebook asks for username/password every single time Firefox is restarted? I do not use cookie-cleaning extensions. They also send a 'login attempt' email and phone notification every time.

Hi, I am using Firefox 118.0 for Fedora that comes with my Linux distribution (Fedora 38 Kinoite). Everything was working fine, but as of today, when I try to start Firefox from a taskbar, my entire desktop goes black for a second and then returns to normal with Firefox not starting as if I didn't click on the icon at all. However, if I open the Terminal and run Firefox from there, everything works fine. I am not sure if the problem is related to Firefox, KDE Plasma or Fedora, so I will start here. I attach my system info below.

Terminal output (Firefox works fine from here): $ firefox Crash Annotation GraphicsCriticalError: |[0][GFX1-]: vaapitest: ERROR (t=0.40708) [GFX1-]: vaapitest: ERROR Crash Annotation GraphicsCriticalError: |[0][GFX1-]: vaapitest: ERROR (t=0.40708) |[1][GFX1-]: vaapitest: VA-API test failed: failed to initialise VAAPI connection.

My Firefox 118.0.1 on Win 10 (all current updates) is creating literally thousands of profile files daily. For example, at this moment there are 3957 profile files with names like

in the directory C:\Users\(user)\AppData\Local\Mozilla\Firefox\Profiles\ywlawdlc.default-release-2\cache2\entries

There are also thousands of other profile files in folders from previous dates.

What is the purpose of this many profile files, and how do I stop their creation in such quantities?

After upgrading Ubuntu from 18.04 to 22.04, I attempted to import my old profile data into the new version of Firefox (118.0.2). All attempts following the instructions at [https://support.mozilla.org/en-US/kb/recover-user-data-missing-after-fire...] failed.

Following the instructions at [https://support.mozilla.org/en-US/kb/how-run-firefox-when-profile-missing...], I deleted the profile.ini file.

Since then, Firefox does not open. I still get the message "Your Firefox profile cannot be loaded. It may be missing or inaccessible." The only option is to press the OK button at which point, FIrefox closes.

There is no current information in the crash logs and I can't find any error logs.

When I select in Settings>Privacy & Security>History, that a history should never be saved and close the Settings tab, the next time I go to Settings, the option is replaced by the setting, that saves a history according to customisation and there's a check mark to always use the Private Mode. Apparently Firefox doesn't keep or save the setting. I learned from https://support.mozilla.org/de/kb/privater-modus that saving a history according to customisation with the option to always use the Private Mode enabled, is the same as never saving a history, nevertheless it should be possible to keep the setting (as the setting exists). How can I solve the problem?

Hi; Search engine does not open in new tab. This is not how it used to work. Not sure when this started, possibly when windows updated to Win11(2 weeks ago), but not sure. I think there used to be a setting for opening a search in new tab, but I can not find it. I have "Add search bar in toolbar" checked. I use DDG as search engine. I did lookup in FF help but found 10yr old answers. I am sure many things have changed since then.

Also when searching FF help is there a way to sort by newest first?

TIA

How do I stop them, please?

Also, is there a legitimate connection between Mozilla Firefox and brnok.stoneheartseeker.top?

Hello, what's wrong with the bookmarks thumbnails, that they don't display properly (not as the site's logo), only some default ones that look ugly. Only some tabs have thumbnails. I have freshly installed firefox on a new PC and I've been using it for another day and nothing changes, I visit these websites constantly and these icons still look like this. It will stay like this or is it some browser error ?

Youtube playlist videos won't play continuously after 2-3 video

Hello, everyone.

4-5 days ago, I've noticed weird YouTube playlist behavior. When I start playlist and switch to a different tab (or minimize browser) first video will play normally and it will autoplay the next one. But after finishing playing 2d video (3d in some cases) video will just stop at the end of playbar and not autoplay the next one in playlist. Playlist for example: https://www.youtube.com/watch?v=giUY_pEKTzY&list=OLAK5uy_nKmglmCCbx14WeFyH8e7YGYcL5skYwnp0&index=1

It's rather easy to replicate, I can record desktop video if needed.

Expected behavior: I can start YouTube playlist playing and switch to a different tab or minimize browser and playlist will only stop after playing last video in said playlist (unless "Loop playlist" option is enabled).

What I've tried to do so far: 1) Googling: I only was able to find old thread and the culprit was extension: https://support.mozilla.org/en-US/questions/952608 2) Disabling Extensions and confirming issue in Troubleshoot Mode: Did not help 3) Clear cache & cookies for YouTube: Did not help 4) "Allow Audio and Video" autoplay for YouTube: Did not help 5) Confirming issue in another browser: Works as intended in Opera 6) Checking about:config: I'm not that savvy with Firefox config to understand what may cause an issue. Tried to change media.block-autoplay-until-in-foreground to False. Did not help, rolled it back to True.

What I have noticed: 1) Firefox recent update: 118.0.2 October 10, 2023: Correlates when I started experiencing this issue. 2) YouTube playlists plays next video continuously just fine if I don't minimize browser or switch to a different tab. 3) There is a Firefox extension that does exactly what I don't want in my experience: https://addons.mozilla.org/en-US/firefox/addon/no-playlist-autoplay-for-yt/ I installed it just to check. And yes, it does what expected and it is similar to what I'm experiencing. Although it stops playlist after finishing first video, my issues go into the affect after playing first video. (Deleted it after testing)

Before posting I've tried a few different things and here where things gets extremely weird: 1) It works just fine in Firefox if I log out from my YouTube account: (Incognito/Main tab) Do not work if I'm logged in, even in Incognito. However... 2) It works just fine in Opera if I'm logged in my YouTube account. 3) It works just fine if I open playlist in mini-player. (Current workaround)

After all that weirdness I attempted to Clear cache & cookies for YouTube and it did not help once again.

P.S. Yes, I use YouTube as a music player. :)

Although I have disabled all relevant "sync" settings in Firefox, the browser is still syncing tabs across my MacBookAir and my iMac.

To make matters worse, tabs in Chrome and Safari sync to Firefox tabs across devices as well. The sync occurs in both directions.

I am not logged into Chrome or my gmail account.

Specs: MacBookAir: early 2015/ OS v. 12.7 (Monterey) iMac: Retina 4K, 21.5-inch, 2017 / OS 12.6.8 (Monterey)

Things I've tried:

  • Turning off syncing in Firefox on both devices.
  • Signing out of Firefox from both devices.
  • Disabling "sync open tabs" via Firefox preferences
  • Renaming devices from within Firefox Sync. (The name always reverts to the previous one.)
  • Reinstalling Firefox
  • Deleting cache from both Firefox and Chrome.
  • Restarting

Images are from toolbar on iMac when Firefox is open on both computers. Any help would be most appreciated! Thanks!

there used to be an add on called roomy bookmarks that stopped working so people found ways around to replicate it and it works on win 10 but I just switched to Win 11 and this solution doesnt seem to work anymore for me, anyone know if i need to change anything?

    Locate your firefox profile folder, in this article they say where you can find it: http://kb.mozillazine.org/Profile_folder
   Find your profile folder mine was: C:\Users\***\AppData\Roaming\Mozilla\Firefox\Profiles\***.default\
   Locate a folder called chrome (if it doesn't exists create one through your O.S) must be lowercase
   Locate inside chrome folder the file: userChrome.css (if it doesn't exists create one through your O.S, google how to create a .css file on notepad) Chrome must be cased as shown above
   Add the code: https://pastebin.com/1r6cc8hW
   Restart Firefox, now you are done, if you don't want text to be displayed within the icons just remove the last line. 

This is the line of code i have in css file that works for me in my win 10 machine.

/*

* Recreates the basic functionality of the popular Roomy Bookmarks Toolbar add-on in Firefox 57+.
* Uncomment the section with the functionality that you want, leave all other sections commented.

* The tooltips on long hover (showing bookmark name and link) are unaffected.
