Hello, I've recently had to send my mac for full refurb. They wiped everything and I had to reinstall all applications. But after I installed and singed in to my Firefox, I could not find my bookmarks. I have searched online and followed several steps but still can't find the bookmarks. Please, can you help me recover them?

I opened a profile that I had just used recently to a blank tab bar. I closed it and the sessionstore-backup folder did not have a recent backup, The most recent about a week old.

Just for testing, I tried to restore with one of the upgrade.jsonlz4 file, about 2 weeks old, but it also had no session. I then restored one that was 2 months old. That one had a session

Now, Firefox no longer generates the upgrade.jsonlz4 files

Yesterday, 50% of my bookmarks were deleted and now I can't bookmark anything. I tried to restore my bookmarks to several previous dates, but I received the following message each time:

Unable to process the backup file.

I tried to bookmark different websites and no bookmarks are saved now. I updated to the latest Firefox today and no change.

Hello,

I just had Firefox overwrote a session restore I had open for a long time with a few hundred tabs. Is there any way to see prior session history or backup these sessions without manually copying the files? If not will these features ever be added?

Thanks

I'm not exactly clueless, but I'm not an engineer. For some reason, I had three open Firefox/Mozilla browsers open on the taskbar but connected to one icon. Today, I've lost the browser with all of my frequently used sites, and tons of research, family, friends, World War II, finances, etc. The other two browsers had one tab, and maybe ten-fifteen tabs, respectively.

How do I restore the main browser?

Thank you for any assistance.

I use the Firefox browser.

While online, as I pressed a letter , Firefox closed, and its icon on the Taskbar disappeared.

After finding a Mozilla support page, and updating the browser, I found that all of my Bookmarks had disappeared.

And even worse. I tapped the 3 bars in the upper right corner to go to > Settings > Privacy Security > Saved Passwords. All of my Passwords were eliminated too. This is disastorous.

Help, I'm 71 years old.

Dzień dobry, podczas wymuszonej przez was aktualizacji, znikneły mi wszystkie zakładki Mozilli Firefox z ostatnich 15 lat!!!!!! Prosze o zwrot, apropos to jest skandaliczne zachowanie waszych informatyków

Seit dem 25.12.2025 habe ich meine Lesezeichen und Passwörter, wahrscheinlich nach einem Update oder einer unbeabsichtigten Fehleingabe nicht mehr zur Verfügung. ich möchte meine Firefox-Version wieder auf den Stand vom 24.12.2025 zurücksetzen. Was kann ich tun oder kann man auch telefonisch Kontakt aufnehmen in deutscher Sprache?
