There might be something wrong on your system. I switched a long time ago but sometimes run chrome to compare performance, and it's on a par.

If you come across a site where the performance is noticeably worse than in Chrome, it may be worth notifying the owner. The alternative is to live in a Google-controlled dystopia.

There is an exception to this - G sites routinely run slower on FF, but this is very likely how Google wants it to be.
