I opened up my computer this morning just to find that all my passwords where erased. i was logged out of my account so i logged back into my normal one and i found that all my bookmarks, addons and history was all there. the only thing that wasnt where my passwords. im running kubuntu 18.04 and have updated my pc and restarted it and none of my passwords showed up. is there any way i can recover them or will i have to add them all back manually.
