@boilingsteam except this is just not true..
As long as Google has enough money to pay as many engineers as it wants, Firefox will always be playing catch up.

You think mozilla at some point in the past didn't care or something?

It is impossible to compete with someone in the web space who defines the actual specs that will end up in the browsers. HTTP3 and many others things are basically created at Google/Alphabet.

Firefox is just trying to survive at this point, finances do not look good
