Gnu IceCat is the GNU version of the Firefox browser.IceCat feels a little faster and use around 60mb less ram than firefox.Gnuzilla-FSD version is 60.7.0 released on 2 June 2019. Here in Void Linux IceCat is regularly updated and the current version is 68.9.0. AFAIK no other linux distros have IceCat available in their repos.A big thanks to Void devs:folded hands:
I used to use it but moved over to firefox because compatibility broke with some extensions. But after reading this post, I am giving it a go again. Right now I notice that it doesn’t support however Firefox tells websites I am using a dark theme but it’s not a deal breaker.
