Firefox Community Forum

Hello, I've got a bit of an issue with Sync. So, my current sync profile is outdated by ages, and I'd like to delete it completely and update it with all of the information on my desktop browser. But, when I try to enable sync on my desktop it overwrites my desktop profile with all of the outdated information saved on Sync. I can't seem to find anywhere to delete the saved Sync data so that I can upload a new copy.

I hope someone can help, thank you!

It's a bit weird, I got the thing you get when you migrate to a new browser - asking if you'd like to migrate history and bookmarks. I closed it because I've used firefox for years.

When firefox opened proper, I got a tab asking to restore the previous session, along with a "Welcome to firefox" tab. As well I got a few popups for other things, basically just stuff you see when you open firefox for the first time. A couple of extensions opened up a landing page that should only open when you first install them.

All my bookmarks and browser history is there. The settings have all been reset to default. The extensions are there but all of their storage seems to be gone, like my dark reader extension no longer has the exception sites on it. Ublock has the ad count reset and most importantly all my custom rules are gone! I have spent years making hundreds of custom rules, and quite a few took hours to get right. I am sad about losing that.

Does anyone know what might have happened?

When I was looking at my about:config to see I saw these things in the modified settings.

there's quite a few settings here and IDK which are relevant. The ones in the pictures where just the first couple and I show them because they seem to have something to do with this situation "auto migrated" - when it seems like the browser did this because it thinks it migrated, the first screen I got was asking if I'd like to transfer my bookmarks and history (and good thing I closed it,or it might have deleted those too).

‘After I bought a new Dell computer 11/23 I lost all my prior FF bookmarks that I used for years. Is there a way to get them back if you have a record of them?’ Thank you for any help.

Every time I restart my laptop, Firefox loses all preferences and configurations whenever I reboot my laptop.

When I open Firefox after restarting my laptop, it acts as it's not connected to the internet, and won't load any pages, it just keeps loading indefinitely.

It's still connected to my Mozilla Account, but Sync is turned off, and all configurations and customization seem to be reset to default.

To fix the "connection" issue, I go to Menu > Help > More troubleshooting information and select the Refresh Firefox... button.

After that, I can go and activate the Sync option again, which will get all my bookmarks, extensions, etc.

Finally, I go to about:config and change the value of browser.uiCustomization.state to set my toolbar customization as I normally use.

I've tried reinstalling Firefox, removing all Mozilla-related files and folders, removed registry entries, but nothing worked...

I really enjoy Firefox, but this is too much of a headache... This is my last attempt to solve this issue, or I'll be forced to switch to another browser... At this point, even Internet Explorer will do

Firefox v131.0.3 running on a x64 Windows 11

I've added Firefox to multiple PCs and phones in the past. I just upgraded my PC and had to reinstall Windows so I also had to reinstall Firefox. It seems like everytime I install Firefox on a new device or reinstall it it keeps re-adding my bookmarks. My bookmarks menu is now like 400 bookmarks long, most of which are duplicate bookmarks or bookmarks that I deleted long ago. How can i stop this from happening and how can I get rid of all these duplicate bookmarks without having to delete them one at a time?

Hello,

My bookmark folders (containing all my bookmarks) disappeared in this latest update. I followed the instructions indicating how to restore my bookmarks, selecting the date I wanted to restore from - but it didn't work. I got an error message saying, "Unable to process the backup file." How can I get all my bookmarks back?

Thank you!

I've used Firefox for decades. One thing I love about it is I've always been able to close Firefox and when Firefox starts up again, it always remembers all of my windows and all of my tabs. That is, until about 3 or 4 weeks ago. All of a sudden, when Firefox restarts, it usually loses many if not most of my windows. Sometimes some of the unopened windows are still available in page history. Other times, they are not. This is really really bad. I need Firefox to work like it always used to work, where you can shut down windows any time you want, and when you start Firefox up again, all the windows and all the tabs come back, no ifs ands or buts.

Hello, I reinstalled windows and I want to synchronize my data from my email from which I send your message and every time there was no problem, but now it does not want to synchronize the data as if it does not exist, what is the problem because the data is important to me and I cannot to access Kind regards.

I lost all my bookmarks. I tried all recommendations to repair without success, and decided to accept it and start again yet am unable to add bookmarks now - hitting the star doesn't work.

I refreshed firefox, deleted and reinstalled.

I keep getting the error message "The bookmarks and history system will not be functional because..."

When I try to restore I keep getting error message "Unable to process the back up file" - doesn't matter what date I choose.

What the hell has happened? I've had so many links and pages saved - now all gone...!!
