My Firefox bookmarks, tool bar, bookmarks menu, etc. all disappeared apparently due to update 153. As stated, I use Windows 11 Pro but my Firefox apparently is telling me that I'm on Windows 10. This makes no sense to me but that is how I'm reading my screen. I have no idea if the update caused the disappearance of approx. 900 business-related bookmarks what happened other than things were fine one day and then 18 hours later all was gone.

I went through the well written article by "AliceWyman, Tonnes, Michael Verdi, scoobidiver, John99, Swarnava Sengupta, Jason, user669794, adampeebleswrites." I followed article text as best I could getting to my profile per the Application Basics, Open Folder and found three "sqlites." Here is where I get concerned because after following the article's direction, nothing happened.

I apparently created a new profile per no. 153, but I also (apparently) have profiles back to no. 147 per a list I saw onscreen -- but I cannot seem to do anything with that information when I click on those folders. Articles tell me that I can revert back to a prior profile, but I cannot do anything with these prior profiles. At this point I'm fearful of doing anything more.

What do I do now? The real question to me is whether anyone in the Mozilla support community knows of someone who can help over the phone or log in whether as a volunteer or paid consultant. The other question is whether Mozilla is capable of fixing this bookmark issue that apparently emanates from so-called updates. The articles appear to assume that Mozilla / Firefox have had this problem repeatedly in the past.

If someone is aware to such a volunteer or consultant please forward the above and ask him/her to contact David at < [redacted email from community support forum] > Thank you all.

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?

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.

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.

I recently updated Firefox on my computer. After that, I can't find my old Bookmarks.

Also I find that I am UNABLE to add any new Bookmark. When I click on the 'Star' in the browser toolbar, there is nothing. Before I used to Get the Add Bookmark tab and a place to SAVE, now there is nothing.

Even after I type in the URL in the address bar, and open up the required page, I am unable to Add it to my Bookmarks.

Please Help!
