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?
The day Firefox shutters its doors is the day the internet truly dies. Almost every “alternative” browser is chromium under the hood. Google’s next big plan is basically constructing a walled garden around the internet (at least the HTTP part) via complex DRM. Eventually, if you want to access an actual web page, it’ll have to be via a Chromium browser. Hell, even today a shitload of websites I visit on FF just don’t fucking render correctly and I’ll have to fire up a chromium instance just to access them. That’s only going to get worse with time.
