I actually think it’s a good thing they are seeking other income sources. After all Google is both their competitor and main income source while being under investigation by the government. Firefox barely manages to keep up with Chrome as-is. Nevermind if they had a team a fraction of its current size. It’s just not really practical for a project this size and scope to have a small plucky team. It needs a big organisation of some kind behind it. Ideally one like Google or Microsoft who can pull income from more profitable projects to pay for better browser engineering. It’s also needed so they can have a say in web standards. An organisation like that also has more ways to make money from their browser like with ChromeOS and Android. Firefox actually tried to make their own smartphone OS, to be honest I am annoyed they didn’t succeed. It would have given us a real alternative to Android while giving them needed income.
