> I'd argue it's still the best browser out there—Chrome, Edge, and Safari are backed by the biggest corporations in the history of the world behind them
You didn't define what makes a browser 'best' so hard to argue there (although I would argue otherwise, at least on Mac, Firefox is nowhere near being the 'best' browser if by 'best' you mean fastest, most battery efficient and best native OS integrations).
Also Mozilla is 'backed' by the same corporation 'backing' Chrome (90% of its revenue coming from Google).
So I believe case could be made that there is a very real correlation between Firefox market share and the decisions happening at Mozilla.
