Firefox 社群討論區

I had to erase my laptop and am in the process of resetting it up. I used firefox prior and am trying to see if it is possible to restore all my previous bookmarks etc. I was told it automatically backed them up.

My mac froze, force quit did not work, unplugged it, turned it back on, all bookmarks were gone and not able to add new ones. Would like to restore old bookmarks and add new ones.

I have updated firefox on my desktop, with quite some open tabs, where Firefox promted that after the upgrade all tabs would be restored. However, none of them were restored nor could I find them in the history. I guess I had all opened in a private window. IMHO the prompt could have warned for this and now I have to reconstruct all these tabs with my memory.

Is my assumption right?

Recently my installation of Firefox (Windows 10, 64 bit) updated. Now my bookmarks are apparently gone--or at least I can't see them. Furthermore, I can't bookmark anything at all, so I don't have the option of laboriously rebuilding my library of bookmarks. I don't know how to recover what I had, or even if I can at all. Nor do I know how to alter settings so I can add new bookmarks. Could someone please assist? Thanks.

Hello, yesterday my 2025 Macbook restarted on it's own and my Firefox browser restarted too, and while it brought me back to all the tabs I had open, every single one of my bookmarks has disappeared. I only have one profile. All my extensions are working properly. The bookmarks sidebar and toolbar are both completely wiped clean. I've tried to go through the backup and restore options provided in this community previously, but going into my library and clicking 'backup' or 'restore' has done nothing. How can I recover my bookmarks? I had been saving small business links for years that are now just gone for seemingly no reason.

FF 153.0b4 this time, was only a few months ago when FF did this same thing last time! But now its an updated ver and still messing up! It's getting more bloated (But most software is) and trying to do to much and things are going WRONG alot more often. FF (Mozilla) used to go years between data losses and now it's MONTHS! Get your act together Mozilla.

    FF wasn't even updating it self, and I haven't changed anything in days. Worked fine yesterday but when I opened it today, the 4 windows opened but they didn't want to open there tabs (most of them have less than a dozen). The main window showed my menu bar, recent browsing icon and a mostly blank tab bar except for the new tab on the far right, none of the other tabs were loading or even showing up, but the space was there for them. I even just left it sit there and chew on things for about 15 minutes before I decided to exit out (file/exit) and try again. This time my other 3 windows loaded just fine but the main window with around 2 dozen tabs was BLANK! and NO recovery options! Recently closed tabs does show tabs I closed on it before the meltdown but NONE from the LOSS. Nightly does not show any in the Tab sync either (but it may not have been up long enough to sync). There is a previous window, but that is not the one I need to recover (Ironic that it will save a window with 65 tabs closed a week ago and let me recover it but it won't let me recover a window with only a couple dozen tabs from a couple hours ago). Wish I could remember how to wright complicated batch files, then I could make one that would back up the profiles after I close FF, that way when it screws up I could just copy the last backup in place and be working again. And all I would need to do is just put a time code in the profile name to make incremental backups and decide how long to keep them for with out over writing. SEE how SIMPLE that would be for you to do Mozilla? It's been how many years that you've been working on FF and it's predecessor and still no profile backup and restore? And to make things worse, most of the databases used are encrypted in some way so as to be NOT user friendly. We can't even import an old backup or profile parts if we need to recover something or look at something. You make it SO hard to recover from a crash when one happens (and they happen more often than they used to) and even just to back up our info even if we could recover it. You were a great browser, now you are broken and barely adequate bloat ware and getting worse. Problem is that your still better than chrome and edge crap.

Logged on to find this message. Followed "Fix" set as best I could (I am puter dumb) with no joy. "Manage Bookmarks" is completely blank. All wits end, Please HELP!

Noticed the issue yesterday (5/21/2026) . My tabs were not what I had when I closed it the night before but from several hours earlier .

I googled for some help and was told to go , Help>More troubleshooting information> Profile Folder>sessionstore-backups and look for the backup I want , and rename as sessionstore.jsonlz4 (deleting the old one) . That did not work so as a temp fix I am using the session manager extension. 

How to fix this ?

Windows 11 for a start, just recover my account if you can, forget about AI primary password and all the rest of the rubbish, have the decency to have a phone helpline for people
