Donate mozilla
Their FAQ (https://wiki.mozilla.org/Donate#Don.27t_Mozilla_products.2C_...) contains pretty important information.In particular, it answers why one should donate when Mozilla Corp makes money through corporate deals (e.g. Google and Yahoo search commissions). The answer is that all the money Mozilla Corp makes is reinvested back into Mozilla Corp (salaries etc). The Mozilla Foundation -- a non-profit which wholly owns Mozilla Corp -- is not funded by Mozilla Corp, but relies entirely on donations. Mozilla Foundations is responsible for philantropic education and awareness campaigns.So this link is not about donating to Mozilla Corp, where the bulk of Firefox development happens. It's about donating to Mozilla Foundation.
