I believe Firefox could raise a lot of money through donations. If they make it clear that Firefox donations will be solely used for Firefox development. Also ideally add a quick survey to donations to see what the "donating" userbases values are. My issue with donating to Mozilla is that it is too broad and they have many products I don't care for.
I use Thunderbird and donate to it because I feel it's more focused. I believe Mozilla still can use the funds for other stuff but at least I am donating for a clear project.
