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.

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.

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).

Hmm. We’re having trouble finding that site.

We can’t connect to the server at marvelsearch.com.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox Developer Edition has permission to access the web (you might be connected but behind a firewall)

i am using a local dnsserver and firefox is connected to it. is this the reason? if so how can i disable this? other firefox features are working beautifully.

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.

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

Hi,

I have logged out from some device (laptop) today. I had approx 150 tabs over there I would really like to recover. Is there any chance to get them back?

Kind regards Grzegorz
