My Windows 11 computer crashed recently. Before restoring windows I was able to backup some data files. I thought that I had a Firefox backup, as I recorded a folder called “Old Firefox Data” It contained a Folder called “2eguguhi.default-release” of size 751 MB. It in turn contained 7,708 Files, & 2,269 Folders. When I re-started Firefox on my “fixed” Windows 11, It was a virgin with no History & no Bookmarks; my old configuration was lost. I tried to follow the advice Fro Mozilla Help But to no avail. It was not able to detect or recognise the Folder in “Old Firefox Data”

Am I Lost or can someone Help please.

When prompted Firefox does not load correctly, but once I get yahoo emails loaded I can access them. Can I uninstall & then reinstall firefox to try to get it to work. Will I loose all my emails? I’m still using windows 10.

Today, I once again had to refresh Firefox Due to my eBay page being rehashed and not usable, but I forgot about my Facebook and after the refresh found I have now lost almost six months of chat history (most recent of which is very important to me), and I just can;t find a way to recover it. Please advise me what to do. Kind regards

Hello Community

Can anyone help me.

After using clean my Mac, I accidently deleted Firefox and important bookmarks. I have searching for the boikmarks folder in TimeMachine but cant find them. Any ideas please?

Best regards, Graham

UPDATE: efforts to fix this have revealed that it's likely the release of Profiles didn't cause this problem although I speculate there might have been an inadvertent time bomb in the release. I will open a different question searching doesn't turn up the fix. If I would delete this post if possible.

FF 148.0 was running on MacOS with my profile as a folder (e.g, trb618r9.default) under Firefox. When I looked in history it was empty so I restarted FF, none of my tabs were there, and TreeStyleTabs didn't display. Investigating I see a new folder named Profiles that has a profile in it with the trb618r9.default name but not all the data in the original trb618r9.default. I renamed the "new trb618r9.default" and moved the original trb618r9.default to Profiles and restarted FF but still am not seeing the original fxxx data which still exists.

Screenshot of finder before I renamed etc. as described above shows the two same named profiles.

How can I recover?

My wife's old Windows 10 HP laptop quit working last week do to some Operating System failure while it was trying to do an update. It finally did a reboot and now it is useless, at least as it is! It will NOT complete the boot process after trying all of the options offered. All that I am able to is exit out of Windows to a "DOS prompt." I am able to get to the Mozilla Firefox folder and others contain within. The new Windows 11 laptop I bought her is working fine with a fresh Firefox browser installed about a week ago. What she wants is her web links, settings and saved passwords "copied" from the old laptop and installed on the new one! We have no idea how many there are to retrieve! I'm hoping that there might only be one folder that I can copy via "command line" prompt to a USB drive and move the file(s) to the new laptop the same way. Can anyone tell me what I need to know? Thanks in advance! Tim O.

I am looking to Restore yesterday Firefox have lost all my pin tabs when I opened this morning the browser how can I get my old stuff back? Please help me out. Thanks

Attempted to update FF using the 140.2.0esr.msi file. During install it asked for a location of bookmarks (seemed off, like a new install) so the process was stopped. All FF profile files appeared to have been untouched based on their dates. So the following directories: \AppData\Local\Mozilla\Firefox\Profiles\oeg1ubpo.default-esr \AppData\Roaming\Mozilla\Firefox\Profiles\oeg1ubpo.default-esr where both copied to a secondary directory as a safety precaution. Install was restarted and it appears to have again installed a new version with no bookmarks, extensions or password DB carried forward from the previous install, which is not what I wanted.

Can this be corrected, by moving the copied profile back in.

Thanks, Brian

What seems like ages ago Firefox stopped displaying bookmarks I addition it would not add new bookmarks nor restore the existing ones. I've gone through all of the corrective procedures listed on and off but nothing works. As a final attempt I deleted the program and reinstalled it. No change. It seems to me that perhaps a missing file from another program or system is missing. Maybe!

I have been using an alternate system for some time. When installed it had no problem finding all of the Firefox bookmarks and placed them on the menu bar as "Firefox Bookmarks". I have no issues with using them but all new ones are stored in the current browser. Thus the new ones do not go into the folders previously set up. I've avoided moving them manually to the new system due to the volume but I am ready to bite the bullet.

I prefer Firefox but it's just not working.

Can anyone save Firefox for me.

Over the last 5 or 6 months, Firefox seems to have lost the capacity to remember my open tabs if my Mac is forced to restart. These open tabs are vital to my workflow. If this can't be solved, I shall have to migrate to another browser, which is something I do not wish to do.

My Firefox version is 147.0.4; my computer a Mac Studio 2025 M3 Ultra; my OS Tahoe 26.3.

Please advise.

Ich habe die Passwortliste bei Einstellungen aufgerufen und die war leer und alle gespeicherten Passwörter waren weg. Ich habe sie aber nicht gelöscht. Wie kann ich die Liste mit den Passwörtern wieder wieder herstellen ?

I updated Firefox last week. A few days after, I discovered that when I signed into Firefox, I couldn't find my bookmarks or extensions that I'd had on it before. I tried the "Import bookmarks" menu, but it only gave me option to import from Microsoft.

Then, I saw two firefox icons on startup menu. When I hit a faded-out one, I got into Firefox and did see my old bookmarks and extensions. When I clicked a fully colored icon, I got into Firefox but couldn't see my old bookmarks and extensions.

I saw firefox listed twice on my "uninstall" menu. I uninstalled the later one. Now, there's only the fully colored firefox icon on my startup menu, but when I click it, I still don't see my old bookmarks or extensions.

Trying to log in to my account a few minutes ago to get help, I was told the password I was using didn't work, so I came up with a new one. When I logged in after that, I got a message saying my old data might not be available.

Is there any way i can get my old bookmarks and extensions back?
