Hi the Waterfox 2020.10 X64 is outdated. I have installed the new version G3.0.2 (64-bit) when starting patchmypc it will installing an outdated version please be aware don t support outdated browsers check the update release channel aurora from Waterfox.
They now use version "G3" instead of an actual version number in Waterfox version in the registry! Therefore Patch My PC can't detect it for now!
We are hoping they will change or fix this soon so we can update Waterfox again.
