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?

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.

I have been using Mozilla Firefox on my mobile phone or PC since 2015. So, after so long, I found the Gmail that I used to log in to Mozilla from 2015 to 2018. Now, if I log in with that Gmail, will the previous history or data be restored or will it be Mozilla's?

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?

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?

I removed the solid-state SSD drive from my physically-broken Windows 10 HP laptop and connected it to my new Windows 11 HP laptop using an external adapter, wanting to move the contents to my new machine. But already I find that only about 3/4 of my bookmarked browsing favorite sites and document files are among the items that I can find on the old, externally-connected "D" drive (D:>USER>OWNER>FAVORITES). I tried visiting some of the bookmarked sites and hitting "bookmark this page" for each, but then none showed up on my new Windows 11 machine's firefox browser bookmarks sidebar. Perhaps they are being put elsewhere because I am opening these sites from my old drive??

I probably need to first understand if and how much that the two drives are still operating separately, so not cooperating with each other in the way I had hoped. I know next to nothing about any of these things but have used the Firefox browser and documents files for many years without too many issues.

The regular version of the browser is open with a bunch of pinned tabs and a private version. And!!! If you close the REGULAR version , but DO NOT close the PRIVATE one before that, then when you try to reopen the REGULAR one, ALL OPEN WINDOWS AND TABS will BE DELETED!!! WHY?!?!

And these tabs are not saved in history, because they WERE NOT active in this session!

Where do developers' hands grow from?! Well, this glitch was a couple of years ago! But now?! A month of work preparation went to hell because of Firefox failure... How do I restore tabs that were just blown away by the browser?

Cannot restore Firefox profile from a large HTML backup file (197 MB) after migrating from Windows 10 to Fedora

Hello! I am having trouble restoring my old Firefox profile after migrating my system from Windows 10 to Linux (Fedora). I have a backup file in .html format that is 197 MB in size (originally created on Windows). When I try to select and restore it using Firefox's built-in recovery tool, it throws an error: "Something is wrong with this file. Please try again with a different file." What I have tried (and what didn't work): Moved the file from an external drive to the local Linux Downloads folder (the error persists). Tried dragging and dropping the file directly into Firefox (the recovery page loads, but the restore buttons are missing or inactive due to security/script restrictions). Tried renaming the file extension from .html to .zip to extract its contents manually, but the archiver threw a "Not a zip archive" error. The built-in recovery script fails to process a 197 MB HTML file, likely due to size limits or memory handling on local files. Could you please advise on how to properly handle and restore such a large backup file or extract my data (passwords, history, bookmarks) from it on Linux? Thank you in advance!

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

What the hell has happened to the support environment? I've tried to resolve two big issues recently, and I can't find anything of value. I've lost the ability to pin an extension to the toolbar after losing my entire profile on this computer, tabs and all, using Tab Manager. I can't find a way to recover the profile, so I've given up on that. Now I can't get my most-used extensions back on the toolbar.
