Everything breaks on icecat 3.6

[Joshua Ismael Haase Hernández]

Hi there.

I'm using icecat on gnewsense 2.3,
when I installed icecat 3.6 from
ppa: https://launchpad.net/~gnuzilla-team/+archive/ppa

        1.- The add-ons didn't worked anymore,
        this was fixed by reinstalling the addons.

        2.-The «Bookmark all tabs» function doesn't
        work.
        
        3.-The  «Recently closed tabs» and «Recently
        closed windows» doesn't work.

        4.-Icecat doesn't open pages from last session
        on startup.

        5.-Icecat doesn't check my RSS subscriptions
        automaticaly.

Greetings.
Joshua Ismael
