Eh, even as someone who on a global political scale is left leaning, I've been hesitant to donate to Mozilla. I'd love to support the browser development, but the fact that they siphon off money from that to support political activities and organizations (especially when some of them are downright corrupt, like BLM) turns me off from that.
When I want to donate to a political organization, I'll do that directly. What I want Mozilla to do, most of all, is keep firefox (and by extension gecko) alive, and thereby maintain internet freedom.
20% is huge on cheaper (i.e not horribly expensive) EV 's when you'll already be on the edge of your range for daily use. Luckily though, most people don't live in northern latitudes.
