To be clear, I do use Firefox and haven't even installed Chrome/Chromium for a long time. But given that Mozilla is inching closer and closer towards ad agency, it's only a matter of time that Firefox will open up the same issues that Chrome has.

The argument of Firefox vs Chrome is not siloed and inherently includes the argument of what their respective developers do and don't do. If we didn't need to include them in the face of such an argument, there would be little reason to switch away Chrome.
