I've just got this idea that there is a need for a forked version of Firefox that would provide right out of the box tools for web development. Like FireBug, YSlow, FireCookie, LiveHTTPHeaders, etc.
Maybe the fork should only include those extensions or take a further step and implement them in existing chrome.
The reason I'm thinking about this is that right now I have two Firefox profiles. A "browsing" one which has only one extension and a "development" one which has lots and lots of extensions. The advantage is obviously that the former is faster than the latter. Maybe if aimed from the beginning at developers, a forked version would bring some speed improvements and other niceties.
What do you think? Any volunteers?
