I still use Chrome for convenience in regards to school and business, but I've been using firefox for all personal internet usage for almost a year now, and I think it was a good decision. I installed a free adblocker and use duckduckgo as my main search engine and it's honestly crazy how much this improved my internet experience. Switching over is incredibly easy and overall really positive. I would like to be able to completely cut google out of my life, but that won't be able to happen while I'm in school, since the school uses gmail and google drive for nearly everything, but having school and play in separate browsers is honestly kind of nice, anyway.
It probably doesn't make that much of a difference in reality, especially since I don't know a lot about web design or coding and mainly hang out on tumblr, so a lot of the actual differences in functionality don't really come up in my usage, but overall I think firefox is better and would recommend it.
