Article seems pretty flawed. Relevance is a vague metric, and the author relies pretty heavily on data related to government site visitation, which seems subject to bias toward certain types of users.
Market share is likely still incredibly low, but Firefox’s relevance should be spiking right now due to Google’s shenanigans with Chromium. The fact that like 90% of revenue for its for-profit wing is from Google is still troubling.
Any alternative views out there?
It’s behind in many ways. Firefox is perfectly functional, but lacks the finish and capacity to implement modern standards as fast as the competition can.
I’d say “the competition has the advantage of being backed by billion dollar companies”, but Mozilla is funded mostly by Google paying for being the default search engine as well. Which only makes it weider that Mozilla is actively moving away from investing Firefox; they’re trying to be an “ethical AI” company now.
