On Mobile, I stayed on Fennec for at least a year to avoid Fenix... Collections are a bit of a pain to setup... but either way, if most extensions still work, why do they disable them by default? We went from thousands of extensions to about 10 with that Fenix "upgrade"

Well, ok, but remember that for the past few years it's only the crippled WebExtensions.

Isn't it already there? At least, there appears to bea thing labeled NoScript in the add-on manager download list. Says it's last updated in April.

(That's Firefox Android release version, not a nightly.)
