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.
