Just for anyone here switching: Don't get firefox; get firefox developer edition. It's firefox but you don't need to pay Mozilla $20 and go through verification to local-load browser extensions you write for yourself. (you can do this on non-DE firefox but you have to reload extensions every time you restart browser)
I've been off Chrome for a while after using it for about a decade. Firefox is nice to have around, but ngl, it's behind on standards and some of its implementations are wack. Its performance on video is poor, and its memory management relatively awful, especially if you're the kind of person who leaves your computer on for months at a time; be prepared to open a new tab and copy-paste any "HUD" tab URLs you leave open (e.g. CNBC for the top ticker). I feel like the kind of person who buys an Intel GPU, and I have some thoughts about Nvidia for pushing me here.
Does DE really persist local add-ons? Last time I tried, it still unloaded them on browser restarts.
