Diễn đàn hỗ trợ Firefox

My system was hacked and I had to factory restore it. I didn't write down my login/passwords because I was informed that as long as I had my sign in for FireFox I could restore them on my system.

Alas, I cannot figure out how to do this. I do not have a passkey, a profile or anything other than the email address for my system.

Can you help me? I put all of my important documents in Dropbox and now I can;t access that either.

Anything you can do is appreciated.

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.

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?
