Forum Firefox zajednice

I reinstalled windows yesterday. When I installed firefox and signed it, everything was fine. However, this morning, it seems to have removed 80% of my bookmarks. When I try to restore from the bookmarks yesterday, it just gives me the ones that I have this morning. I had tons and tons of resource bookmarks for my work that would be almost impossible to re-find in some cases due to the current state of search engines. Is there any way to salvage them? It seems like sync believes they never existed, but it DID sync them yesterday??? Please help.

Sessionstore.jsonlz4 does not contain the current tabs, so where are they? After losing all of my tabs I copied the sessionstore-backups. They were quite large. Obviously they must contain my lost tabs. But now the current sessionstore.jsonlz4 has the very same large size. However, the lost tabs do not show up when Firefox is launched! And yet the few tabs – I’ve tried one, two, and three – that were open when Firefox is closed do show up. And the large size of each “new” sessionstore.jsonlz4 does not change at all! BTW I have tried inserting each one of the backups and nothing changes. The current tab or tabs shows up, but not the lost tabs. What is going on?

Lors de la dernière mise à jour de Firefox, j'ai retrouvé un dossier sur mon bureau appelé "anciennes données de Firefox" Faut-il garder ce dossier ou le mettre dans la corbeille? Merci de votre réponse
