Interestingly, I had the opposite experience. I've been using Firefox for many years after moving away from Chrome because it was too slow. Nowadays, I've been thinking about moving back to Chrome because I tried a recent version of Chrome, and it ran faster than FF. FF does have some nice features like privacy and some really cool extensions. But it's gotten slower and there are some webpages that don't work for me unless I fire up Chrome. But since I've been using FF for many years, and have all of my favorite extensions and logins saved, it's tough to go back.
