Firefox gets like 90% of its revenue from Google.
Keep Firefox independent and donate: https://donate.mozilla.org/en-US/?form=donate
But donating your money can not make firefox independent.It will only make firefox more revenue.
Google wants to keep mozilla afloat to stay out of anti-competitive allegations.
If mozilla gets market share, google will defund them. That mozilla have a money will help.
Also mozilla’s other projects are also good ;)
Some of Mozilla’s other projects are good, iirc there was a journalist a few years ago who chronicled how Mozilla had donated a lot of money to other charities unrelated to it’s goal rather than reinvesting in the business so that it can try to ween off of Google reliance.
