I develop on Chrome all day every day and I cannot relate at all to these people saying it is full of bugs and crashing all the time. Nor do I find that Firefox is faster.

Chrome dev tools are still the best in the business, and Chrome just works.

Also I did a memory usage comparison on Chrome and Firefox 2 months ago and Firefox was using more memory by quite a bit (and got worse the more tabs you had open.) And this was Firefox with NO Flash and Chrome with Flash.
