How to install Firefox Rapid Release via PPA for v 1.15

[hubby4]

If you simply try to install firefox via the terminal, it will install the snap package. The rapid release PPA version has hardware acceleration enabled by default. This needs to be turned off since it doesn't work properly with the Rockchip drivers as of May 2023. Unlike Chromium, Firefox can be configured with hardened security and privacy options. I prefer using the Arkenfox user.js to configure my browser.

1. Open the terminal

2. sudo add-apt-repository ppa:mozillateam/ppa

3. Copy and paste ALL of the following lines and type enter.

echo '
Package: *
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 1001
' | sudo tee /etc/apt/preferences.d/mozilla-firefox

4. sudo apt install firefox

5. Open firefox. Do NOT toggle fullscreen. Go to Hamburger Icon-->Settings-->Performance. Turn off " Use Recommended Performance Settings". Turn off "Use hardware acceleration when available". Close firefox. Open the browser again to see the settings take effect.
