I you think projects like Mozilla and Firefox are important donations can really go a long way. If enough people even donated ~$5/mo to projects like this, which is less than lots of people spend for Spotify or buying coffee, it would make open source privacy respecting projects a lot more viable.
I know this kind of goes against my other comment stating that I'm super worried about losing the only viable free and open browser out there (my only browser), but: what's keeping me from donating is the bad aftertaste of the money being used for frivilous things. I don't want to fund their bookmarking service. I don't want to fund their VPN rebranding effort. I don't want to fund their authentication services. I don't want to fund their voice recognition services. They're probably great, but it's the browser that's absolutely essential and irreplaceable at this time!
