Firefox 社群討論區

Hello,

I'm writing because I’ve encountered an issue with the tab groups feature in Firefox.

Some time ago, after a browser update, I noticed a new feature that allowed me to group tabs thematically — I could name each group (e.g., "Study", "Work"), choose a color for it, and save and close groups to reopen them later. I found it very useful and used it a lot.

Last night, I decided to declutter my browser and closed several tab groups using the built-in menu. A bit later, I shut down my computer, but perhaps too quickly. This morning, when I turned my computer back on, Firefox was very slow to start. After a restart, everything seemed to work fine again, and the open tabs were restored.

However, all my previously saved (but temporarily closed) tab groups disappeared. In the tab group menu, I can now only see the ones currently open. I’ve searched through all the settings and history but cannot find any way to restore the missing groups.

Is there any way to recover the tab groups that I had previously saved and closed?

Thank you very much in advance!

I was asked to create a new profile in order to keep using Firefox, despite never having an account. After I clicked okay, it opened the new version of Firefox, but without all the passwords, bookmarks and history of the past few years. This is really inconvenient. I have since then made an account, but the fact that I can't find any of this data anywhere has me worried that every time I update Firefox it will wipe my account.

Every time I make Firefox full-screen, it immediately crashes and shuts down. I have restarted the computer, uninstalled and reinstalled Firefox, but it still doesn't work.

Every time I open a new site or webpage, the automatic translation window pops up. I don't need translations and I have to choose "don't translate this page" again and again. I've searched everywhere on Firefox and I can't find a way to stop this. It is extremely intrusive and annoying. I don't understand why Firefox should decide for me what I want and what I don't want. Has anybody solved this problem.

When I open Firefox, the master pw window opens with data showing. I can x out of the window & continue. So my data is exposed to anyone who hacks into my desktop PC. WIN 11 64-bit. Please help.

I was trying to setup 2FA on my Mozilla account on Firefox pc browser (140 version). The process completes without issues with Aegis authenticator app, I download the backup codes and I even get the email confirming the recovery phone number was added. On the Mozilla accounts page 2FA turns to enabled. (I'm on Windows11 with latest Firefox browser version)

However after a simple refresh, it turns back to disabled. I repeated the process and same thing happens. Same even on Firefox Android. What could be the issue here?

When I read a thread and then it shows comments I can't read them on Mozilla anymore

I went to Google Chrome and I can read them so its something with my browser

It's really strange (I'm still trying to understand my relatively new Windows 11 laptop), bookmarks have been where I'd expect them for a few days, then this morning, it's as if Firefox has done some sort of clean/re-arrangement. The bookmarks had disappeared and there wasn't my usual array of sites available along the top. Then by clicking on a few things on the right (Firefox) 'most used' re-appeared, then later the toolbar is there on the right, I'd really like it back on the left And also I'd love to know whether I might have done something unconsciously which caused this.

I have a Snowflake add-on, which requires WebRTC for connections. But WebRTC is not permanently active in my Firefox browser. See image. I activate WebRTC by toggling the config variable media.peerconnection.enabled into 'true' and the add-on works. For some time, only! After a couple of days it is back to 'WebRTC not detected'. What is wrong?

I often use the key combination Ctrl+Alt+X in Google Docs when on different devices but it doesn't function properly when instead it brings up the AI sidebar gadget. Removing the sidebar button doesn't really help and it's annoying. So how exactly do I turn off the key combination for the sidebar?

Hello, FF support forum,

I think I have seen a Container retain my login to a site when I open it again after closing it. Is there a way to configure Containers so that they are mini versions of the dump-cookies-temp-data when I close Firefox entirely? I would so love that functionality.

I have been getting this error for about a week - absolutelyu no changes have been made to my usual use of the PC and browser. There may have been Firefox/Windows updates installed. I'm not doing anything different to the usual work I do.

I have tried using a new Firefox profile with no cached info carried over, this doesn't solve the problem. I have no extensions or add ons. I do run Avast, but haven't had this problem before.

Crash report: https://crash-stats.mozilla.org/report/index/1fe71926-ad8e-4592-b103-9874f0250722#tab-annotations

NB: I do not usually get the opportunity to submit a crash report when these crashes happen.

Application error: a client-side exception has occurred while loading (see the browser console for more information).

where is the browser console? how do i fix it never had an issue with until the last two days?
