To be frank, Chromium’s security is much better than Firefox and is faster as well. If Google had no monopoly over the browser market and allowed uBlock Origin, I wouldn’t really use Firefox and use something FOSS chromium based instead.

Mozilla is not a good company at all. They are a pretend privacy company while paying the bills off of your data and Google’s sponsorship.

So I am using Firefox not because it is good but to use uBlock Origin and to prevent Google’s monopoly.
