Firefox takes at least 4-5 seconds to start up. Following that, webpages sometimes load after a second, and sometimes I have to wait as much as 10 seconds. This is despite a stable 200Mbps internet connection and a good PC (Intel i5 4690k, 16GB RAM) I would like to continue using Firefox as my broswer, but Chrome loaded my websites consistently in under a second. I should also note that my only add-on is uBlock, which Mozilla's troubleshooting page even claims improves performance.
