I was a FF driver for ages and now making the switch to Chrome based browser simple because it's faster and websites are all tested against Chrome / Safari. I see both of these issues manifest IRL on a weekly basis. Why do I want to burn up CPU cycles and second using FF when Chromium is literally faster.

I use FF because of uBlock Origin, and also because it has built-in support for SOCKS5 proxy connections, which I use to access stuff at work over an ssh tunnel.
