I can't say that I find Chrome any faster than Firefox. What made me try Chrome for a while now is that Firefox constantly crashes when trying to view video's on Youtube and other site. wierd thing is, my PC's at work and at home are basically mirror images of each other, but only the work one crashes. No idea why that's happening. But Now I'm using Chrome at work and Firfox at home.
One thing that bothers me about Chrome, when you go onto Gumtree, you can see the initial gallery of items, but once you go into the ad you can't view the pictures for some strange reason. Also on some websites and forums there would be a popup notifying you of new PM's, Chrome doesn't show these or even give you the option to allow them. On other sites it does.
