I'm speaking this in a pragmatic rather than idealistic terms. Donations have no use when it doesn't go to developing the browser itself (which, to be honest is the most urgent issue right now. Users are having all sorts of performance and instability issues in major websites and switching to Chrome instead.)

This is not an argument. How do you know that developers of other companies are better compensated? (The money distribution follows your ideals)

Let’s talk about the product.

Sure, let's talk about FF Android removing extension support and only adding it back in a very limited way.

Compared with the alternatives which don't support extensions at all? What is your point?

They did it for technical reasons, and one of the first extensions to be supported was ublock origin.

The alternative was to keep going with the previous version of the app, which even supported installing extensions directly from an xpi. It's nice that they support an adblocker or two, but I need much more out of my browser than that.

"Technical reasons" doesn't really cut it. There are frequently technical reasons involved in making a bad decision. That's not a justification.
