Diễn đàn hỗ trợ Firefox

My computer died today due to water damage, which means I can't turn it back on again. I got a new computer, I've looked all over the Firefox support websites, and can't find a solution as to how to get all of my Firefox data onto this new computer. I tried the profile page, but it looks like a profile for my old computer's Firefox never even existed. I have no idea where to find any of my old data.

So I reformatted my computer today, but the process allowed me to keep all my personal files. I had made a backup in my appdata for all my passwords and bookmarks like Firefox allows when you're in Manage Passwords or Manage Bookmarks. After the formatting, I sign into my Firefox account, and it Syncs almost immediately. When I go into my appdata, the profile has been overwritten by the new sync, meaning all my passwords and bookmarks are now no longer available. Is there legitimately anything I can do??

I had issues with my computer which got me into a situation where i had to delete all partitions of my drives, starting from 0. Signing in my firefox account in a fresh win install suddenly recovers NOTHING and i am now panicking as i had very important accounts & passwords, bookmarks, tabs, extensions, etc. I have tried other devices too without any luck. I need help recovering all these asap.

So i was using firefox in Linux recently and now because of linux issues, i switch back to windows. I logged in with same id but sync is not working. I had a long history of passwords, extensions and bookmarks. Also opened tabs and all but the account sync is not working. I even verified if this is the same account i logged in with in linux as i have 2FA and in the app it says this is the email i used for it. Please help me ASAP

I have an email account blocked (jgcaller129@gmail.com) and have tried the sync tab at the top corner of my computer. It sends a message with a number to this blocked email to unblock it- how am I supposed to get an email from you on a blocked account. How do I unblock this account. I have tried several times with the same result now the icon to sync isn't there anymore. PLEASE HELP This email is very important to me. You can send a reply to an alternate email account (also linked to Firefox -jgcaller15@gmail.com).
