Thanks for the tips. I've tried out enabling Tracemonkey, which I've found makes things a lot slower when javascript was concerned. I went to Chromeexperiments.com and tried some of the examples there. The one I tried "Ball Pool" with and without javascript.options.jit.chrome/content enabled and I've found that when that is disabled, it's a lot quicker.

I like the change of google search settings though, I hate having to use Google Mobile when I can use full-fat Google instead.
