I have been using old-style profiles for a long time, but they didn't work so well for me. The new profiles system was great - specifically that each one was a FF instance that could be opened and quit independently of any others (and most importantly had a different icon). I setup 5 or 6.

But i quit all my FFs due to memory issues. Then after restarting a FF, it was an instance from the old profiles system and there was no profiles item in main menu (under three horiz lines top-right).

Going to about:profiles didn't show them (as expected).

I started from command-line to launch FF with Profile Manager and after selecting a profile that way, then there now a Profiles menu item. However it empty.

I had a look and there is a ` ~/Library/Application Support/Firefox/Profile Groups` that contains a number of sqlite files and each has a -shm and -wal file also. I looked in the profiles table for each of these. 1 lists all the new profiles I created and one points to default old-style Profile instance that opens (ie. Profiles/Main-Firefox-Window).

about:config - browser.profiles.enabled is true

I also noticed a browser.profiles.forceEnableRefresh but it appears to be undocumented.

My question: HOW can I restore my new profiles? I put some work into icons etc.. and of course their history, so i don't want to have to recreate them.

Does anyone know how to restore a previous profile? I had a situation like this: I had Firefox 140. I decided to upgrade to 147. Then I upgraded to 145 and all my data disappeared. The system is Linux Ubuntu.

In Firefox my previously working Bookmark folders are empty, everything I previously bookmarked is gone, and now firefox will not let me create any bookmarks to replace them .

Hi, there.

After performing the most recent Firefox update, I was greeted with the "create a new profile prompt", rather than having it open my old one. When going to "about:profiles", ALL FILES in the Root Directory of my old, default profile have the same date as the update, or after. Not a single file is older than that and all my history and bookmarks are gone. The option "Restore Previous Session" was not shown after the update.

PLEASE HELP!!

Thank you.

PS: This happened on a Macbook Pro. All other profiles are the same as they were before the update, having kept all history and bookmarks.

Mozilla, in their infinite wisdom, sent me a note about something new in firefox, by displaying it in a new instance of Firefox.

It wasn’t until I closed my normal session, that I realised a new instance of firefox was also running, and shut it down on.

In shutting the new instance down after my usual session, it overwrote all my normal tab settings🤬

Q1. Are my normal tab settings recoverable? Q2. Why did Mozilla think it a good idea to open a new instance of Firefox to send me information, rather than simply open a new tab.

NB This is in Windows 11

I hate the new Firefox!!!! It lost all my data from the old one, bookmarks, passwords and everything. I want to be able to revert to the previously installed version but I can't find the data. The old one was so familiar.

I'm 83 years old and have trouble remembering a lot of things but I was very happy with the earlier version!

After most recent update all my bookmarks and passwords disappeared and I cannot seem to recover them. This is extremely frustrating. Has anyone else had this happen? I tried using the recovery process but it did not work.

I've been using the firefox broswer on a mac for the last couple years and I installed the duckduckgo search feature into firefox today, also firefox updated today when i turned my computer on so I'm not sure which one is the culprit but I lost all of my bookmarks and saved form data. Is there a way I can get my bookmarks back? I wasn't using an account or signed in ever but would that info be saved on my computer?

Following a restart procedure on Windows 10 today, all my saved Firefox Passwords have now gone! (Firefox 144.0.2 (64-bit))

Can I recover them?

Please note; I will read and review any replies but cannot respond until tomorrow, as am at work now.

Thanks in advance! Andy.

I recently bough a new computer and transferred all my data, passwords and bookmarks to it. Each time I opened my mozilla browser I was encouraged to create a profile , but each time I just continued without creating a profile. Finally today I was not given an option to proceed without creating a profile so I did. But now all my passwords and bookmarks have disappeared. When I try to find them I am advised to load my previous profile but this is not an option the only profile I have is the one I just created with the missing data. Can you please tell me where the appropiate files are stored and how can I recover them. Thanks

Firefox's new version was installed but after downloading and opening, when it opened, NONE of my tabs opened. I tried 6 times to no avail. I need my tabs. How do I fix this?

I restarted my computer, but my tabs did not reappear. I restarted, but I have lost all my bookmarks, and I cannot add bookmarks. All Mozilla recommendations have failed.
