Hi chuck598, several other ubuntu users have this problem too. See also: https://support.mozilla.org/en-US/questions/1332346 Try to install firefox from the apt repository. #open the terminal #type ''sudo apt update && sudo apt full-upgrade'' (this command will update all your applications and can take a while; if you don't want to update your apps, leave this step out) #type ''sudo apt install firefox'' or if "firefox" is not found ''sudo apt install firefox-esr'' (you need root privileges)
