Indeed. Donations go to Mozilla Foundations for their activities (advocacy and whatever). Firefox is developed by Mozilla Corp.,whom can't legally receive donations.

Stop with this excuse and stop Insulting people. I've been on Firefox for nearly 20 years, but Mozilla has ruined it for me little by little. The last straw has been the horrible UI redesign. So I switched to a Chromium browser. Tell Mozilla to make a better browser and to listen to their community, instead of blaming people for using what serves them best.

It's fine but I find mildly irritating the fact that they have removed the tab dividers.

In my case is because the stuff I buy has to be mine. It's a matter of principle. I root and degoogle all my phones and install custom ROMs on them (and FOSS apps from external stores, such as fdroid). I couldn't deApple an iPhone, so it'd kind of limited for me. Plus, frankly speaking, I couldn't care less about RCSi/Message, it's not like there aren't enough messaging options out there.

I don't think so. Reddit is making exception for 3rd party apps with accessibility features, so RedReader should be exempt from paying to use the API. Or this is what its developer said.

In my understanding, RedReader will continue working.
