A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

  • Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
  • For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
  • I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

An hour ago I had all of my Firefox bookmarks. Ten years of meticulously filed and regularly culled references that I use multiple times daily. I rarely log out of Firefox sync, so that I can keep them up to date.

I now have no bookmarks and no tags.

For some context, two things just happened simultaneously. So, I'm not entirely sure which is the culprit.

1) Firefox just updated and I rebooted my computer.

2) Norton 360 updated sometime in the past two days. I attempted to familiarise myself with the new interface. Foolishly, given the track record of Norton-360-for-breaking-your-games, I ran the disc cleanup, which recommended I remove approximately 400 Mb of data. Norton stated this data was temporary files. If they were indeed my bookmark history, nowhere did Norton indicate they were bookmarks. Also, never have I encountered a disc cleanup that wholesale wipes bookmarks. I do hope Norton is not the culprit and this is just a glitch, because if this were due to Norton having no safety net for deleting an entire library of bookmarks - and they can't help me restore them - then that will be the final nail in the coffin for me doing business with Norton.

The suggestion to go to Import and Backup in Firefox, then click Restore, offers only the option of Choose file... - and then launches nothing.

Currently, I'm seeking any means of restoring my bookmarks. Any help would be appreciated.

I had presumed that I was taking reasonable measures through my Firefox Sync settings to protect my bookmarks and ensure they could be restored in the event of accidents. If these bookmarks are permanently lost, the amount of work I've just lost is quite the blow.

Edit No. 01: After writing this, my Bookmarks Toolbar is also now empty. Perhaps it had wiped earlier, but was merely waiting for a refresh to take effect.

Edit No. 02: Also, it seems I am unable to create any new bookmarks. I shall read the help suggestions relating to that now, to see if it's a relevant issue.

When I open any stream, it takes about 2.5 seconds from the start of the page loading to the appearance of the stream image and playback. For comparison, in version 137 it took about 1.0 seconds.

I tried to launch the browser (Firefox 138.0.1) in troubleshooting mode, and also created a new profile, but the problem remained.

I also downloaded portable versions: 137.0.1 - everything is fine. 138.0 and 140.0a1 - slow loading.

I also have Zen Browser installed (the latest version is based on 138.0.1) - everything is fine.

The camera won't turn on in the Firefox browser for Google Meet or Zoom. It says it can't find the camera or that it's turned off. I have checked my Windows 11 settings and desktop apps have access to the camera. I have also checked the settings for each of the sites and use of the camera and microphone are allowed. Autoplay is enabled too. The camera works fine in other apps and in other browsers.

All of my addons are disabled and won't re-enable!

They all say "addon name" could not be verified for use in Nightly and has been disabled. See attachment clipboard00.jpg

If I try to install an addon from the recommended extensions settings (for example "return youtube dislike ") I get a message bubble stating "The Addon downloaded from this site could not be installed because it appears to be corrupt. {OK!}" See attachment clipboard01.jpg

The message above about addons appearing to be corrupt happens if I go to any of my current addon pages and try to redownload them.

I have tried several sites including Udemy, YouTube, and radio programs, no sound from Firefox. The problem started in the middle of a Jit.Si session. All of a sudden the sound disappeared. I thought that restart Firefox would help, then restart the computer would help. But the problem has continued. The speakers is turned on the volume is up, just not a sound from Firefox. What to do?

I'm running Firefox browser 88.0 (64) bit, and have been trying since before Xmas to upgrade it to a newer version. It's installed on an older Dell laptop running Ubuntu 16.04 LTS (which I've also tried repeatedly to upgrade without success).

I've tried to upgrade both through the UI, but also tried using the command line in Terminal. Per advice in other threads, I've found the best mirror site and changed my settings to use that, but still no luck. Even the preliminary "sudo apt update" via Terminal fails; the first error tells me that the public key is not available. I assume that's the place to start, but don't know how to correct it.

I'm up against the deadline for updating my browser, and would very much appreciate any help you can provide. (Please note that I'm posting from a newer computer, so automatically generated info about my system won't apply. See the screenshots for that info).
