Trying to move away from FireFox.

I know that there is LibreWolf and GNU IceCat.

What are the pros and cons for each?

I tried GNU IceCat and I don't know how to install extensions. How to get extensions for GNU IceCat? Is it easier on LibreWolf?

I need the following extensions:

• ublock origin
• send to MPV player
• privacy badger
• Distraction free youtube
• Unhook
• LeechBlock NG
• Privacy Badger
• Tab Session Manager
• KeePassXC-Browser
