It gets a fixed amount of money from Google for using them as the default search engine. But what I meant was Firefox has no means to actual generate an income in its own right. Mozilla have tried. The reactions have not been good.

The money from Google is practically a donation at this point. It's not exactly an altruistic one but it's not exactly a pure business transaction either given Firefox's current market share.

Is it even possible to donate money to Firefox development and not to greedy CEOs?

You can't donate to Mozilla Corp full stop. Besides which Firefox users are strongly opposed to "nags" in the browser as Mozilla have found. Even wikipedia, with it's massive reach and yearly nags, "only" makes ~$120 million. Firefox could never hope to reach anything like that from donations alone and it needs many times that number to keep pace with Google Chrome's practically unlimited funds.

Your first bad assumption is that the amount of money is fixed.

What will happen to this donation if the outcome of the anti-trust is against Google ?
