Firefox is significantly slower than chrome and safari in my experience.

Firefox is faster than chrome and only doesn’t work on badly built pages and webapps (like intelex)

Chrome isn't faster anymore in my experience. FF has made great advances in performance.

Firefox is not faster than chrome for me

Firefox is not as performant as Chrome is. This is something a web developer will have come across, if not an average user.

TBH, Firefox seems snappier than Chromium-based browsers. Check your extensions.
