I never said that, actually just said exactly what you did : that Google pay them to still have a competitor.
But that’s a big problem, because that make them competitors just in name, and using their browser won’t change that sadly. Another problem is the lucrative part of Mozilla that have made a number of bad decisions over the years with firefox, and are partly to blame as to how it fell out of favour.
To be clear Firefox is far from being the worst browser out there, it’s not what I am saying, and it can have forks, we can also edit most of the crap out of it wich is great. But it would be silly to consider it a spotless software run by saints. That’s all I am saying.
I would even go back to it or (better) a fork of it if I could get the features I use in Vivaldi without using countless and broken (or non savy) extentions, because I’d still find that better than using something based on chromium (even if there is a dedicated and seemingly good intended team behind it). But I would still not find it ideal, not without that lucrative side of Mozilla hanging onto firefox and that damn Google pay.
