I use Firefox everywhere. I tried Chrome recently and it feels a lot faster, but in the end the ability to block ads and trackers (everywhere, including mobile which is where I do most of my browsing) is more important than a bit of speed. If Firefox is fast enough, then faster is pointless. But as can be seen in this thread, some people believe it's their duty to look at ads so for them the extra speed is probably a nice bonus (and perhaps partially compensates for the extra work their browser is doing).
