EDIT: why is tab auto-backup limited and FF folder???

Verified but still... Unless it is open-source where you can compile it yourself, I don't know...

EDIT: Feedback: Could you please make it - so you can make folders for saving sessions??? I read thousands of pages, I won't be able to discern previous sessions, once I have many of them!!! That would help a lot THANKS! As tags don't work for everything! At least there is search and you can rename session names!!! Also could you add renaming names of Firefox windows? BTW thank you for making this addon, firefox devs have iq 10...

Devs of these addons don't account for many practical things, this is almost perfect ergo 5 starts.

ALSO CONSIDER MAKING SEARCH ACROSS ALL TABS, I CAN'T FIND ANYTHING with my 1000 tabs. Chrome session buddy had this...

UI is little bit counter-intuitive, at least the first time, I was scared to click something to not mess up my windows...
