The latest firefox update introduced tab groups, something I've been eagerly waiting for ever since chrome released it!

However, my firefox's tab groups don't hide the tabs correctly. In the video demo I see that when you click on the name of the tab group, it should collapse all the tabs and hide them.

In my firefox, when I click the tab group name, the tabs don't get hidden as expected.

Here is a video that shows the bug I'm referencing: https://imgur.com/a/8ewW1a2

I tried disabling all my extensions and restarting firefox, also tried in private mode, and it still was having the same experience.

Are there any about:config settings that I might have accidentally changed that could be causing this?

Thanks!

Hello, everytime I try and upload a video on YouTube with firefox, the video gets stuck at 0% processing,

This never happened in my 4 years of youtube and recently (a few weeks ago) this starting happening. I use firefox to stricly upload videos, and use chrome to browse with my other account casually.

Now Im forced to upload using chrome but I want to still use Firefox to upload videos. anybody know why this is happening? I've cleared cache serveral times and it still won't work. I have no adblockers etc.

Maybe after update, or i dont know why, but now. when youtube (or any other videoplayer) in fullscreen - taskbar menu is visible (Is on topscreen). In google chrome problem is not repeats. I'm using StartAllBack app for classic start menu, but till that day all was fine. I checked on two devices with firefox - the same problem (StartAllBack or windows version wasnt cahnged). Windows 11 24H2

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.

I like using Fire Fox (FF), but I am constantly met with resistance from different organizations which try to tell me to use MS Edge, or Google Chrome. It seems like FF is a problem for them. Now, after successfully using Fire Fox for decades, I can no longer log in to my bank account when using FF. I can use any other browser, but not Fire Fox. I've spoken to the bank, and they point the finger at FF (of course), but this time (unfortunately) I have to agree with the bank. What did FF do that now makes it impossible for me to access certain web pages, or certain features, like "logging in" to accounts?

Can you please un-F whatever you F'd up? Or, please explain to me why I can do everything the exact same way I've always done things when like using Brave, Chrome, Edge, Chrome Cast, and TOR, but can no longer do them when using FF

I logged into my Firefox Sync account last week on a newly re-imaged computer. My old computer is listed under "Connected Services" and for the first few days, when I selected "Sync" from the top right menu, the subsequent menu included the name of the the old computer and the list of tabs. That list of tabs is no longer listed and I haven't been able to find a way to access it. Attached is an image of the menu where the list of tabs was previously listed. Any suggestions are appreciated.

This is the link. I can't send animated images as the text is too small, so I'll describe it instead. It's so hard as a loyal fan, I'm crying.https://www.bilibili.com/bold text。There is a bug. Why does the Bilibili website not display the corresponding screen when I try to move to it? Speed playback cannot be used at all, and there’s also the issue of not being able to use fullscreen on Firefox. Are you forcing me to use another browser?

I followed these directions - https://support.mozilla.org/en-US/kb/export-firefox-bookmarks-to-backup-or-transfer but Firebox only exports this data in the bookmarks.html file and attached image! Bookmarks Menu

How can export all of my bookmarks in Firefox?

To the right of Other Bookmarks Firefox still says "finish Setup" but I've checked everything and run the setup. I can't seem to do anything to correct/clean up this?

Thank you.

With the progressive rollout of tab groups having ended (I am assuming that because they are available by default in fresh installations), I would expect them to be available when I sync with my Firefox profile. However, when I sign in to the browser to sync all my settings, the option disappears. I am more interested in why the rollout never reached me than being told to enable tab groups in `about:options`. The profile switcher is also not showing up, but I am not sure if that is still in beta.

I want to import web page bookmarks from MS Edge. I tried to do it per the settings help page, but I cannot get my firefox bookmarks to populate with the ones from my Edge browser. This problem is a deal breaker that may send me (under duress) back to MS Edge, and I really don't want that.

Hello, after installing a new hard drive (the old one died and I couldn't recover the data), I reinstalled everything on my PC, except that a friend recommended installing Arium (Windows 10.8 LTS). It works fine, except that now I have no way of connecting my Mozilla account to Firefox to recover my passwords and other saved tabs.

I've searched a lot, tried several installations, and even installed a previous version of Firefox, but nothing works...

Do you know why? Is it because of Arium?

Thanks

Logs out of email (gmail) after restarting the browser. I reinstalled windows and downloaded a browser, connected my account, and now when I go to gmail.com and register my mail, everything is fine, it works, but when I exit the browser and go back to gmail.com, there is nothing.

Gmail will not open with Firefox as of Wednesday 5/18/2025. I do not have any adblock extensions running.

Gmail opens fine in Chrome.

Any suggestions?

Can you allow someone to get on my computer to help me? Or do you have a phone number I can call safely to have someone go through things with me, if I need help? It stated when I put it on that is is "poor" in terms of what you did. Maybe I am doing something wrong??
