Just installed the MATE desktop on my Antergos system tonight and when I tried to go on the interwebs with Firefox, the browser wouldn’t run properly. The browser’s GUI was non-existent for the most part, but webpages loaded with no problem. This is weird. So, I tried a similar browser, IceCat (the TNO version of Firefox, LMAO) and got the same behavior. Tried re-installing MATE, but that didn’t fix a thing. Any help out there?
