Not many people had their own website in the late 90s

Your post is pretty nonsensical anyway, but if anything more people had their own websites as a proportion of the web, with Geocities and Angelfire etc. This was before social media, so to have a presence on the web you had to have your own site, and people did.

Without explaining the actual problems you have with Firefox on Android, your post is really pointless.

Also, “steadily approaching zero” is an intelligent an analysis as saying Edge is steadily approaching 100% just because its share is increasing.

Sure, it’s counterintuitive, but so is not bracketing things in ternary operations.
