Recover "lost" data

Browser was broken . I had to reinstall. Now how can get all my stuff back (passwords, bookmarks, seasions, tabs, ….)

If the files were deleted recently, I’d avoid writing anything new to that drive until you’ve tried recovering them. The more the drive is used, the higher the chance the deleted data gets overwritten. Also, it’s worth checking whether the files ended up in quarantine or a backup location before assuming they’re gone for good.
