Diễn đàn hỗ trợ Firefox

Hi, I had to reinstall my windows where I thought my Firefox would sync up upon reinstallation. However, nothing would sync up and the best I could do myself was to import pretty out-of-date Chrome data. When I to my firefox account and scroll to connected services I see my last PC name with its firefox login. Is there any way to recover that data and import to my current device? I read you kept sync data as encrypted data on your Mozilla servers, so I hope that's a viable solution.

So I got myself into a pickle again trying to move my ffox tabs and bookmarks to a different pc. I knew there was something I didn’t like about sync so I avoided that. Until I was having problems transferring my tabs and bookmarks and I relented. Mistake. I had to sign in, not sure why I wasn’t already signed in or why I was signed out. It moved over my tabs fine. But somehow I ended up with some strange list of bookmarks that must be from months ago. If I am stuck I guess I can resurrect what I had although I am not happy at all with this mess. Any way to get back to what I had? It has messed up both the new pc and the original one now. I happened to find some files called session store backups that if that is any good for history those are only for tabs which are fine anyway. Any idea what to do or am I screwed?
