I had something similar happen once with Opera GX, it can be super frustrating . If you were signed into your Opera account before it wiped, a lot of stuff (like bookmarks and passwords) should still be synced to the cloud. Try logging back in and going to opera://settings/syncSetup to check whatâs enabled.
For open tabs, unfortunately those donât always come back unless you had âsync open tabsâ turned on. Sometimes you can still recover them from your history (opera://history).
If sync wasnât turned on at all, then yeah, itâs harder â youâd basically be starting fresh. But if it was, most of your data should come back once you toggle sync back on.
Did you have sync enabled before this happened?
