@stupidjim @campuscodi your comment is accurate.
What makes Firefox better is that it's in fact the only major browser which develops their own web engine. Everything else is just Chromium reskinned. Edge? Microsoft Chrome. Opera? Chinese Chrome. Brave? Cryptobro Chrome.
What's the issue with every major browser being based on chromium? That Google singlehandedly controls the web standards. Yeah, that corporations whose profits come from violating everyone's privacy and that has already attempted to introduce various privacy invasive technologies.
And yes, Safari is also not Chromium, but it's Apple-only and while they release WebKit as open source, there are multiple reasons why no major browser is based on it.
So yeah, using Firefox is a better option if we want to avoid the web to be under Google's tyranny.
