Firefox3 address bar is running very slow. The following is a little workaround for it:
In about:config page, change these keys:
browser.urlbar.matchOnlyTyped = True
browser.urlbar.matchBehaviour = 2
browser.urlbar.maxRichResults = (max results, put between 2-5)
browser.urlbar.search.timeout = (search timeout, put something lower than 100, depending on your needs)
