I'm not sure what happened. I restarted my laptop and when I tried jumping onto Firefox it didn't have my normal accounts on it they were gone and I had to make a new one which means all of my bookmarks are gone, none of my accounts are logged in I am freaking out! What happened?!?!

• OS Version: Microsoft Windows 10 Professional (x64) Version 22H2 (build 19045.6466) • Firefox 149.0 (64-bit) • Thunderbird 140.8.1esr (64-bit)

Have NO idea "which topic best describes my question" from your drop-down list (above), so simply clicked on one.

Restarted my PC; all of my bookmarks disappeared. NOT acceptable. (Or is this just another "improvement" from Firefox . . . ?)

Where did they go; how do I retrieve them?

Really don't want to wait days until there's a response, as I DO USE MY BOOKMARKS ALL OF THE TIME.

Thank you.

I need to find where all my bookmarks are on my computer so I can restore them. My operating system is Windows 7. Even when I try to restore through import/backup and it says it was successful there are none of my saved bookmarks. Can you help in specific steps how I can get these back? From what I read there should be a Firefox file on my computer where these are all saved. Thanks!!

My bookmarks have been deleted after firefox automatical update on 15/3/2026. Does anybody know how to recover them? I have tried to import and back up but I couldn't see a solution . thanks

Installed to new system because old system was updated to Win11 and it failed. Old system is only partially operable. Trying to copy (export and import html files) of the bookmarks to the new system, but even though the import seems to have worked, I cannot get the program to show the bookmarks correctly (or at all). They appear in the Manage Bookmarks window but will not appear on the desktop view. What am I doing wrong? When I import them, I select the All Bookmarks item to copy to but it copies everything to the Bookmarks Menu folder.

yesterday i had all my stuff like every other day, and for some reason i randomly got logged out of alot of my accounts. Now i woke up this morning and the entire browser was reset. no bookmark shortcuts, no tab collections, all account locked out for no reason, what's going on?

I don't have any backup for this, and i didn't think i'd need it, because i'd never delete all ym data for no reason.

Is there even a way to get it back?

I've always had my "Open previous windows and tabs" setting on and its never failed for me but today I opened Firefox and it none of my previous windows opened, it just opened to a blank window and I've tried to recover my previous sessions but my "Recently closed windows" tab in history won't open. Not really sure what to do here as I would like to have my previous windows since I didn't bookmark them which I probably should've done

I had a Firefox session open and had maybe 50 tabs open. I am not signed in and have the browser set to restore previous session every time it is opened. When I last updated the browser, my laptop crashed and turned off before the restore session had opened the previous window. When I restarted it, it was gone and I accidentally closed that window too. This meant the next time I opened it, it restored THAT session and not the one with all the tabs I had accumulated (but not saved or bookmarked). The problem is that some of those tabs had been there for a year or more so it's not possible to fond them in my history folder. Is there a way to restore a PREVIOUS previous session in Firefox or are they gone forever?

RE: After a Mac re-start; despite, having the 'Startup > Open previous windows and tabs' checked in General page; the Restore Tabs option's in both the Top Menu History, and the Top Right Button Menu > History > Mange History were all greyed out. Even the keyboard shortcut to restore all Tabs > Command-Shift-T > Failed.

This has never happened before with Re-starts.

Am I able to restore all these tabs by accessing my Firefox Profile, and what are the exact steps?

Firefox 148.0 (64 bit) desktop.

Thx, Diego

What happened, All my important bookmarks are missing. I have had to log into every account I have, No saved passwords. Really upset. I need help to restore all this information that I need

ello. My favorites have disappeared from my Windows 11 PC. It has happened once before and then I was able to get them back by deleting the sqlite file, now it doesn't work and I need your help with ending firefox processes etc.

Hi there,

I woke up this morning and opened firefox. Normally it opens the days previous tabs and this morning it didn't. When I tried 'restore recent tabs' it didn't do it. When I went into history and found the previous day's back up and tried to restore it also failed. Can you help?

Best wishes, Inez

Man hatte mir eine neue FAssung von firefox eingespielt - firefox VPN. Danach waren meine Passwörter, die Chronik und verschwunden und eine veraltete Lesezeichen-Datei noch vorhanden. Wie komme ich an meine ursprünglichen Daten? Wo liegen diese?

I find that three or four times a month, the links to all my bookmarks disappear. The bookmark folders and bookmark names are still shown but there are no URLs. If I restore to a few days previously they are work again. Why?

Since the last upgrade I have lost ALL bookmarks, History, everything is gone, Passwords also

I tried loading the old profile god knows what it is called, and there's still nothing

WHY DOESN'T FIREFOX BACKUP EVERYTHING BEFORE FORCING CHANGES

TURNS ME OFF USING FIREFOX.
