I have Account Recovery Key , struggle how to use it in order to recover: passwords, bookmarks saved on fire fox Generated: Oct 13, 2025 [removed email by moderator] Debian 13 Xfce Version 4.20 GTK version 3.24.49 Karnel Version 6.12.94+deb13-amd64 Windowing System X11 CPU Intel Core i5-825OU CPU @ 1,60GHzx8 Memory 7,6 GiB GPU Mesa Intel UHD Graphics 620 (3,8GiB)

Firefox unable restore session when switching profiles and instead opening apps installed on the profile I'm switching to.

I have installed Whatsapp web (web.whatsapp.com) on "Profile 1" as a Windows app.

I have some tabs open in "Profile 1" and I switch to "Profile 2" and close the "Profile 1" window with "X" button of Windows 11 but keep the Whatsapp window open.

When I open the "Profile 1" from profile menu, my expectation is that, those previous tabs should be restored, but firefox is opening the Whatsapp web app/window.

Hello!

'I have the menu bar enabled-

When I go to "History", the settings

are greyed out.

I want my tabs back!

I just got a samsung galaxy s26 (old phone is not available); when i accessed my Firefox, my Collections were missing. From other research, it seems that Collections are not available anymore. However, there must be some way to recover the websites that were stored within them, so i can at least rebuild them.

I was switching computers and created a backup file. The type was html oddly. I tried to restore this backup on two different computers and both times it fails during the restore process without presenting a useful error message.

I can only guess that the file is corrupt, but it is only a guess since the error message is useless. It also seems strange that the backup didn't produce any errors (manual backup). Any suggestions?

I have been using Firefox for years. I am not tech savvy. A very tech savvy member of the family recommended firefox years ago (and now says we should use Brave or another).

Does anyone run Firefox? Why is there no contact centre/people? Why do other members have to answer questions? The reason I am losing total faith in Firefox is that it must made me update and restart and every open window I had (and the tabs on each window) have been lost. I cannot retrieve them, which I have always been able to do via "Restore previous sessions". There was so much important information on those windows and tabs from way back - too far to shift through the history. Can anyone give me one good reason to stay with Firefox? Thankfully, there are many browsers to now use. Firefox has perhaps just become a habit and one I should have changed a long time ago. Thank you.

I recently purchased a new desktop due to the previous desktop malfunctioning a bit. The old hdd is still in operating condition and is now a slave in my new cpu. Where can I find the history/bookmarks on the old drive? Is there a filename that is relevant for the data?

Thanks

Firefox has complained for sometime that my profile was created with a newer version than what I was using. I'd click OK, and go about my day. After about a month, I decided to upgrade so it would stop bugging me. When I did, my old profile did not merge, but was deleted, and now I have lost all of my passwords and bookmarks. How can I restore them when the profile is empty?

I used Firefox yesterday. My settings are to open Firefox with tabs restored - but all my tabs (as they were yesterday) are missing and when I go to history, the option to restore a recent window is greyed out. The option to restore a previous session doesn't even seem to be there.

I notice in task manager I have 15 firefox tasks. Could my window from yesterday have opened somehow in the background, but not be visible to me anywhere?

Upon restarting my laptop earlier today, I realized that ALL my Firefox bookmarks have disappeared into thin air. Gone (or, rather, "empty") is my bookmarks toolbar, and my bookmark menu, and everything else. What to do? Thank you.

I had a problem with my Zotac PC and had to do a reset, when done none of my passwords or bookmarks came back after the resety even though Firefox asked for my password and email to send me a code but everything is gone and I have way to reach some of my frequently used sites, can you please help? Thank you, George Morris

I got up this morning and, boom, I am forced update Firefox. Lost everything: history, bookmarks, and passwords. It's suggestions are useless. I have gone to "profiles" (only 2 and none of my information is in either). I am living in Taiwan and half the time the help is in Chinese, which I cannot read. The loss of my information is devastating and I cannot find any real person to help me. There must be a way. Where do I find real help?
