• Firefox version: 149.0b3

Firefox suddenly crashes without any displayed error. Attempt to troubleshoot it in "safe mode" doesn't help (it also suddenly crashes.

• When I had redirected following output: "Exiting due to channel error."
• after restart, I launched "about:crashes", but there were no entries

I just accidentally deleted a day of history, now it has to relearn a bunch of stuff.

Please add support for undo, so that if you do it by accident, you can reverse it.

Hello, I am currently using Firefox Beta and I would like to switch to the regular Firefox Release without losing any of my data (browsing history, bookmarks, passwords, add-ons, and settings). I would appreciate guidance on the safest recommended method. Specifically:

Is it safe to install the Release version over Firefox Beta, or could this cause data loss or profile conflicts?

What is the best way to create a full backup of my Firefox profile beforehand?

Should I expect any issues with add-ons after moving from Beta to Release?

Do you recommend enabling Firefox Sync as an additional safeguard, or is a profile backup enough?

In case something goes wrong, what are the recommended recovery steps?

My setup:

Operating System: [windows 10 ]

Thank you for your assistance.

I really enjoy the new sidebar revamp, but I've had an issue with it recently that I haven't been able to find a solution for. Typically, the settings gear is supposed to be situated near the bottom of bar. However, as demonstrated in the attached image, it is at the top near the bookmarks and history buttons. I have tried reinstalling the browser from scratch, turning the sidebar on and off, turning vertical tabs on and off, and even getting rid of my custom CSS theme for a time. None of these have worked. If anyone knows what the root of this issue is, I'd really appreciate the help.

I have vertical tabs enabled and the "expand when hovering mouse" option is activated (see screenshot). However, the latter functionality tends to glitch at some point in basically every session. I can't tell if a specific action triggers it, so far it seems pretty random. The glitch is that either the tabs are expanded and won't collapse, or the opposite: they're collapsed and refuse to expand when I point at them. Is this feature maybe still experimental? or something? I'm running Firefox 149.0b5 DEveloper Edition on Garuda Linux (Arch based).

Win 11 Pro, Firefox Browser-Developer, 147.0b9, 64bit Problem recently occurred. Example it was working fine this morning and after turning the computer off and restarting later in the day this happens. The image below shows faded access to the password manager. Link that appear do not work: Log in at the header and link in password support highlight in the visible text portion. Thanks in advance for your help

Hi,

The 'Forgot password' option is not working in Firefox. I tried it multiple times and it doesn't send me a temp password/recovery link to my email. It just says 'Invalid account'. Please take a look.

Thanks

1] Topic list is insufficient; 2] I tried to use the share data option of <;tblshg ; > troubleshooting. It could not automatically collect data, so I returned [back icon] to the form and found the form blank. The write-up I had spent well over an hour preparing was simply GONE.

No reply needed, buy that needs a fix. how could that ever pass QA.

There used to be a much more useful interface for clearing specific browsing data (the landscape-oriented one). The new interface is far less detailed to the point of strictly limiting its functionality. There used to be a config setting ("privacy.sanitize.useOldClearHistoryDialog") that could toggle which interface to use, but as of an update in the last week (I've been away without a computer for a while), that toggle does nothing. Is there any other setting that can make this feature actually useful again?

Hello. Why nexusmods.com and loverslab.com are blocked (Secure Connection Failed) on my FireFox Dev Edition 150.0b6 (auto updates)? It bothers me to use it as a default browser. Both nexusmods.com and loverslab.com are ping well and work fine on any other browsers.
