Trisquel Icecat/Abrowser extensions' pages direct to Mozilla site

I was told that the FSF software directory has a list of Icecat extensions. The lists I saw were either just proposed or non-existent https://directory.fsf.org/wiki/IceCat_extensions_(proposed).

Could the FSF directory be updated to work with Icecat instead of the Trisquel site?

Is it possible to host the extensions instead of pointing to Mozilla?

I think yes answers to those two questions would be benefit all GNU/Linux distros.
