I had three Firefox windows, each with a few tabs. One of them also had a “restore previous session” tab which I was planning to open once I had dealt with and closed all of the current tabs. I hit ... something (I’m really not sure what I did: I think I did something with the keyboard while the wrong window was in focus), and suddenly two of the windows (including the one containing the previous session) disappeared. The “Recently closed windows” under the History menu is greyed out: there is no sign of these two windows anywhere. What happened, and is there any way to get them back short of manually going through my entire history of all visited pages for the past week and a half?
I did grab a copy of my ~/.mozilla
folder, but I don’t know how to read it. I’m capable of parsing JSON if that’s necessary, but I’d rather not.
From your
~/.mozilla
folder find the file namedplaces.sqlite
Open it with DB Browser. Go to
Browse Data
tab and choosemoz_places
table.To install DB Browser for SQLite (http://sqlitebrowser.org/):
Try the Session Manager, it gives you the ability to save different sessions in different windows and much more options:
