Firefox Community Forum

Hello,

I just moved from Windows 10 to Linux Fedora Workstation and I used the "Back up and restore" option in the Sync Tab available in Firefox on Windows 10 to save my data in the form of a unique html file. (https://support.mozilla.org/en-US/kb/firefox-backup)

But now that I'm in Firefox on Fedora, this option does not seem to be available (in the Sync tab in Settings). Is there any way I could at least recover my bookmarks ?

I'm using Firefox 147.0.1 from the official Federa repo.

Thank you for your help.

firefox doesnt start and gives me this error If i uninstall the have a fresh, install, everything will work normally until i restart my pc

i cannot install lastpass extension anymore, unless i update to latest firefox version.

this will force me to switch browsers to Chrome or Opera.

I don't like being forced to install the latest firefox.

I intend to stay with older versions that work better.

fix this crap please !

Hello !

How can I retrieve password and usernames that are saved in the login forms of visited websites ?

I know how to see "password and login" in Mozilla settings (Private life & Security / Saved Passwords).

But on some websites, the connection to my account is automatic : password and usernames are saved in the login forms (like cookies may be ?), and they are not present in Mozilla setting and Saved Passwords.

I didn't find anything in the web on my request.

Is it possible te recover this recorded data ?

Thank you by advance.

I had a ton of saved tabs and groupings of tabs. I closed what I thought was my only open Firefox window then downloaded and installed the most recent Windows update. When I rebooted, I did not realize I had left a Firefox window open with a single tab. That Firefox became my default and I lost all the tabs I had. Is there any way to get those tabs back? The tabs I had yesterday, 1/22/2026 are the ones I need.

Hello.

1. How to save a tab group without closing it? 2. How to make individual tabs in a tab group permanent? (So when you close a tab group only the permanent members are preserved.)

Hi I have a website that suddenly started crashing. Hope you can help solve this problem. The problem is on Nettavisen.no. Using Macbook Pro. This has never been a problem before today. Kind regards Sonja
