Firefox has improved a lot in the 18 nightly builds, but yes, its JavaScript speed is still the Achilles heel.

One question, which keeps returning to my mind, is Google Chrome faster or is Mozilla Firefox faster?
Google Chrome as for now is currently not only faster than Firefox, but faster than anything,
at least in my computer. Compared with IE10, Opera 12.50, Safari 5, and Firefox 18 nightly, in many tests and regular browsing.
Chrome -> IE10 -> Opera 12.50 -> Firefox.

Almost all browsers have now very similar GUIs.
