Is Firefox in Linux too slow for you? Does the new Places/URL/Location bar keep freezing every time you try writing something in it? I have had this issue consistently since I upgraded from Firefox 2.x to Firefox 3.0.
I tried googling the issue a zillion times and tried several solutions I found on various forums and blogs but all efforts amounted to naught. Damn, I felt defeated. I finally resigned and reverted to the old URL bar.
