I'm not sure about calling it a new world of open extensions, seeing as Firefox used to support running any extension you wanted and then Mozilla artificially removed that and are now patting themselves on the back for... re-enabling it? Possibly with some extra APIs to make the experience nicer? (Which in fairness is worth something; desktop extensions were wonky on mobile)

They did not re-enabled it.

They provided tools to make the extensions compatible specifically with the android version.

Before they were curating what extensions worked fine in Android and only enabled those, now the developers can take care of that and mark the extension as compatible.
