I had many tabs opened in my Firefox browser and usually I can close the browser and reopen it, and the tabs are still there. After restarting my computer, I went to Firefox and it started with a new session, without the option to restore the previous session. I have a feeling that there is a way to restore these tabs, but in the case that it is not, then I'll just have to accept that. I was thinking maybe a backup file of the tabs, like how the bookmarks can be backed up. The tabs were important, so I just wanted to use this as the last resort to see if they can be restored in some way, shape or form. This is the first time that I'm using this, so I'm hoping that someone can help me with this issue, as I'm sure that I am not the only one that has ever experienced this problem.
