I use Firefox because I don’t like how Google acts with regards to web standards being the de facto standard because so many browsers are Chromium based. If everyone is using Chromium then they don’t need to obey any standards and can just do whatever they want. There needs to be competition in that space. Microsoft Edge becoming Chromium based was a big problem on that regard.

The irony that Firefox is kept alive in part because Google pays them for Google to be the default search option is not lost on me.
