I do web development, it makes no sense for me to use a browser most of the public doesn't use. Also I have a ton of extensions that help with development. Firefox is painful.
Every time someone complains about firefox it's something trivial like this... "I don't like the default download location." / "I don't like how the dev tools opens on the bottom." / "I don't like the way the tab bar looks." Absolutely wild to me that using a browser without an adblocker, forever, is better than spending a week or whatever getting used to the different dev tools.
