I'm on Windows 11. After I added some plug-ins and extensions to replace the ones that went missing during your last update, my bookmarks also went missing. (They were there before I replaced the plug-ins and extensions.) I followed your instructions on how to access my bookmark back ups, and found them. However, everytime, I tried to install one of the backups, I ended up with no bookmarks at all in Firefox.

Please help, I have no access to any of my accounts!

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.

I run normal firefox on linux. Fully up-to-date. Every time I quit the app, it reverts to a version of my profile from a month ago, and loads all the tabs I had open then, and then receives all the tabs that I sent to the device in the interim (~1 month). As I speak, it just caught the 60 or 70 tabs in this window.

I tried changing the name of my profile folder to randomstring.defaultOLD and changed one of the backups to randomstring.default. This didn't change the behavior. I'm still stuck in the loop. I saved my tabs with onetab, because firefox isn't remembering my session anymore. I thought it was something to do with updates, like it only loses its mind upon updates, but that's not true. It thinks it's updating firefox EVERY TIME, because the one time it's loading to 1 month ago it was updating, but I'm 100% sure there are no updates to firefox in my linux. It's just hallucinating.

The articles on restoring from backup are outdated. They say to use an html file. There is no html file. It's just folders for profiles, not html files. HELP!

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!

Firefox unable restore session when switching profiles and instead opening apps installed on the profile I'm switching to.

I have installed Whatsapp web (web.whatsapp.com) on "Profile 1" as a Windows app.

I have some tabs open in "Profile 1" and I switch to "Profile 2" and close the "Profile 1" window with "X" button of Windows 11 but keep the Whatsapp window open.

When I open the "Profile 1" from profile menu, my expectation is that, those previous tabs should be restored, but firefox is opening the Whatsapp web app/window.
