Hi > Can you find evidence that > Pale Moon has made such a commitment for their add-ons repository?
I did not find any such statements. I did find non-free addons though. E.g. FireShot listed here: https://addons.palemoon.org/extensions/tools-and-utilities/
It took some time to find a non-free one, so I guess they are rare like 1% of the total or less.
