Not sure if this is chip specific. My computer freezez and/or firefox/chrome crashes. Running newest sparkylinux 4.1 on a system with J1900 SoC.
Turn off hardware acceleration in firefox (Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available" )
Firefox still crashes but no freeze anymore. Hope this issue will be solved soon. I cannot watch any video in browser for now :-(
