I am trying to restore my firefox bookmarks and passwords from a back up I saved. I am signed into firefox in my browser, I go to restore back up and firefox restars and my bookmarks appearm but I'm signed out of firefox. When I sign back in, my profiles and bookmarks disappear?

I purchased a new computer and installed Firefox on it when I open Firefox for the first time it had none of my bookmarks, etc. As per the instructions on the Webb, I copied the latest profile for Firefox on my old computer and pasted that profile into the users profile folder on the new computer. For some unknown reason, Firefox is not installing this profile. The profile is approximately 330 MB. So I’m assuming there is a lot of data that is stored in that profile folder. Can you please direct me as to how I can use the current Firefox profile that I have from 8-4-26. Thank you

I need my original Firefox account back the way it was. I have no bookmarks, no open page when Firefox opens, and none of my tabs are the same. Please put it back; I don't know how to run my computer this way.

last time my firefox crashed when i was using it and when i reopened my browser all of my history were deleted and they keep telling me that some sort of file is not able to save the bookmarks and history

gerald.r.vargas 4. Aug. 2026, 08:23 GMT-6 Hi, this morning for some reason all the tabs I had open couldn't been loaded. Refreshening the page didn't help either. So I decided to shut down and restart my laptop.

Unfortunately after restarting Firefox only one page and its tabs have been reloaded.  All the others were gone. 

After trying about:support and session:restore it didn't help either, because only the 4th of Aug. was available. Is there a possibility for a session restore from the 03rd of Aug? or the previous days? If anybody has an idea, how to do so, please let me know.

Many thanks, Gerald R. Vargas

Every few days, when I start Firefox, my bookmarks load, but they are non-functional, and the logos to the left of each bookmark name are missing. I can restore previous days sessions, but I lose all of my saved log-ins to frequently visited sites. Why is this happening?

Bought a new Macbook Pro with 26.6.2 and need to transfer all bookmarks from old Macbook Pro 10.14.6, I tried exporting the profile from the old Macbook but it did not work.

I've added my Firefox to a new computer and signed into my account. Cannot find my bookmarks. The only option I see is to import them from another browser (which does not have them). How can I retrieve them?

Every time Firefox updates, my bookmarks are deleted. The still show up, but the links are empty. VERY FRUSTRATING! I have to reestablish every bookmark and that takes up valuable time.

My PC crashed and then upon opening up firefox it forced me to update firefox. Afterwards all windows and tabs disappeared but my browing history is still there. I tried the in-browser restoration but it is greyed out. I tried the session store backup profile data but has no 'previous' or 'back up' files, only 'restore' files that are empty and restore to no tabs or windows. What other ways are possible? It's weird my browsing history anf bookmarks weren't deleted at the same time.

I used to have a whole list of "marque-pages", which apparently totally disappeared after a software update which I never requested. This really is INFURIATING  !!!!

I can't restore my tabs and groups from the last time, the last time i used to have a lot of tabs and groups of taps for my studies and the my mac wanted to do a u[date so it shut all apps running in inculdeing firefox and I can't recover them. even so it's not shown in the browsing histroy

Sometime between 10PM 7/23 and 2 AM 7/24 I deleted my profile by mistake, and all of the data my browser collected has been lost. Passwords, history, cookies, chat logs, etc. No account sync, or official Mozilla profile until now.

Everything is gone and I don't know how to replicate the steps found in this video. Mac's don't conveniently show you things like deleted user data unless you know exactly where to find them. [|https://youtu.be/JWJwmKLqnZs?si=g_g47eHSwoB8XSL5]

I've already tried using Time Machine, but that failed spectacularly.

Current OS is macOS Tahoe 26.5.2, Firefox 153.0 (aarch64)
