The Firefox numbers might not be entirely accurate. A decent amount of Firefox users use a plugin to change their user agent to display as Chrome, as otherwise some large websites will claim their browser or OS isn't supported. It's unlikely they're changing it back, so a slice of the Chrome pie (but probably not Edge) also belongs to Firefox.<br>Two examples I can give right off the bat are Pushdoctor and GeForce Now. Both of which work absolutely fine on Firefox.<br>I've also found a VPN website which wouldn't even allow traffic from Chromium, claiming the browser was outdated. It had a whitelist for Edge, Chrome and Safari in the source code, and wouldn't allow for anything more.,(reply>), Google search on mobile is downgraded if you don't have the Chrome UA.,(reply>), I did not know about that
