IceCat has "Trisquel Abrowser Modifications" installed by default and it cannot be removed from within the browser. However, sudo apt-get remove abrowser removes it without interfering with IceCat.
What do "Trisquel Abrowser Modifications" do for IceCat and do we really need it?
I realize that we need both Abrowser (Firefox-based) and GNU IceCat (Firefox ESR-based) in Trisquel. I didn't realize the difference they were based on until recently.
Is it recommended and safe to run IceCat without or without "Trisquel Abrowser Modifications"?
