Linux Mint 18 $ uname -a Linux mycomputer 4.15.0-39-generic #42-Ubuntu SMP Tue Oct 23 15:48:01 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux $ firefox --version Mozilla Firefox 63.0.3 I was recently experiencing slow load and the spinning wheel and recently disabled hardware acceleration. However, since then, my browser hangs and requires a force quit of Firefox. I'll re-launch FF and restore my session and everything is fine. I'm not exactly sure what settings I can send to you. I have some crash reports, but they are probably because I force close the application.
