IT/Software/Applications/Firefox

This has always been the Ubuntu Default.

I still like it better but it continues to lose market share(Sept. 2021)

There is an issue with Firefox and the DownloadHelper extension when installed as a snap. Firefox must be uninstalled as a snap and reinstalled as a deb from mozilla's ppa.

sudo snap remove firefox

sudo add-apt-repository ppa:mozillateam/ppa

sudo apt update

Add the following to the new file /etc/apt/preferences.d/mozilla

Package: firefox*
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 1001

sudo apt install firefox
