Firefox Community Forum

When I was running a game and updated my graphics card driver, Firefox was running in the background. My PC went completely black and became unresponsive, so I had to force‑restart the computer.

After rebooting, Firefox reverted to a brand‑new fresh‑install state. All my browser settings, login status, local profiles, browsing sessions, hundreds of open tabs and my categorized tab groups disappeared, only the welcome startup guide showed up.

I logged into my Mozilla account on my Android Firefox device. Some browsing history was synced back. However, synced history cannot restore the original tab session back‑forward page history, nor my manually sorted tab groups. All browser preferences, theme and language settings are also lost.

I originally had 4 separate local Firefox profiles on this Windows computer, isolated from each other for different work purposes. Only one profile was logged‑in to my Mozilla account and could partially sync data. The other three local profiles are completely gone. Those extra local profiles were NOT signed into any Mozilla account and were never synced to cloud storage.

In my Mozilla account’s connected devices list, there are two entries both belonging to this same computer: “MARSHAKK” and “Firefox by Administrator on MARSHAKK”, which correspond to my Firefox instance before and after the crash.

I cannot understand the community help articles about session recovery, and I’m unable to locate or restore my old local Firefox profiles and lost tab sessions by myself. Please give me assistance.

I can not access my att.net account. Do I have a setting set incorrectly. I have to go to Microsoft Edge in order to login. When I contacted ATT via phone they said I had to use Microsoft Edge to login. Can you advise me how to correct the situation. I don't use Edge for any other reason. Thanks

When I type in a Google search in Firefox, a red dotted line (not the wavy red line from Firefox's spell check; spell check is disabled) appears. What exactly is this red dotted line? Can I show or hide it in settings? Can I change the setting in about:config? Please help. It's very annoying.

I'm having trouble signing into to some online news sites especially videos. The screen shows activity without actually loading a video or website site. I can't connect, it just keeps spinning.

Had a crash earlier on my macbook that required a restart. Everything else is fine but I have lost all history and bookmark data on my firefox browser. I tried going to see if i had the wrong profile and that was not the issue. I tired recovering the bookmarks in the manage boomarks option but there were no backup files.

I have some important bookmarks i need recovered. Any help would be highly appreciated.

I asked the following question and was sent to this answer, which does not apply to current versions of Firefox: https://support.mozilla.org/en-US/questions/1228045 My question: how do save a username on Firefox for a website without saving a password because I do not want to save the password?

Hi Everyone,

I have tried everything I can to get firefox to work correctly. This morning I woke up to webpages not loading correctly, my emails being unable to be opened, youtube not loading videos, and google result websites not loading. Everything was working roughly 12 hours ago.

I have tried refreshing firefox, clearing my cookies and cache, and uninstalling with revo and then reinstalling. My computer is up to date and I have tried resetting it. Is there anything I need to/ can do to get Firefox working properly again?

Thank you!
