I hope not because I am not entirely sure that the problems are over.
There was discussion here:
https://trisquel.info/en/forum/will-firefox-replace-abrowser-trisquel-8
although onpon4 missed something when they said "Mozilla's trademark policy
doesn't say anything about permitting use of the mark with unaltered versions
of Firefox you compile yourself" because it does and it has the same "no
charge" language: "If you compile Mozilla unmodified source code (including
code and config files in the installer) and do not charge for it, you do not
need additional permission from Mozilla to use the relevant Mozilla Mark(s)
for your compiled version." [1]
