My Dell laptop with docking station and Firefox browser were working fine the evening of July 22 but on the afternoon of July 23 all my bookmarks on the toolbar were gone. I had not touched the laptop during that 16-20 hour interim. When not in use, I have my laptop off and unplugged. I also note (but cannot explain) that Mozilla has me contacting "my account" through Windows 10. I have not used Windows 10 in 3 years (or more). I have continuously used Windows 11 Pro during that time frame.

I have reviewed some of the articles and email exchanges between a volunteer and a Mozilla user whose bookmarks were also inexplicably deleted but found those exchanges confusing, Unfortunately, I'm concerned that I'll do something that further fouls up my system. Email is working fine (the new outlook) and the apps are working fine. Is there a way to recover my bookmarks toolbar? If not, please explain why. Also, since Mozilla seems to wipe out my bookmarks periodically (this is about the third time) what preventative measures are available.

Please post a response or contact David at < [redacted email from community support forum] >. Thank you to all that can help as well as those who can commiserate.

So I wanted to reinstall windows, I had Zen browser and Mozilla Account with syncing enabled (but I only had zen on my pc), and after reinstalling windows I downloaded zen again and got in my account and tried syncing it my literally nothing got synced, no passwords, no bookmarks, no history, and I got no file to manually back it up. Does that mean I lost all my data?

I’m using windows 11 and macOS Tahoe . The back up feature works in windows as advertised. When I came to the mac I searched in vain for the settings. I asked the AI chat bot were the settings are. There are none. I note on your web page you don’t support the mac and provide no information when this new feature will be available. This is a setback I strongly feel you should offer all features across all platforms. The browser marked is competitive and Firefox needs all the features to make Firefox stand out from all the others.

suspected sessionstore.jsonlz4 corruption possible Sync rollback conflicts extremely large tab sessions spontaneous restoration of previously closed tabs during live browsing I am not a techy person. Have seen on Chat steps that can be taken, but it is too complicated for me. Seeking remote or other help. Would like to know how complex an issue this is. I'm having a very tough time. It just restored around 1,000 previously closed tabs. It takes me hours to close them because they get mixed up with the tabs presently opened. It interferes terribly with my work. I'm reaching out to IT companies and then found you through Chat GPT. Please help if possible. TY! This is a Lenovo t16 laptop with windows 11 for home or personal. I haven't had a tuneup for a long time. I read that's not a good thing to do with this issue.
