At one point I forked Chromium over the click-selects-all in the URL bar. In OS X, this was the only application that behaved that way (until Apple recently followed suit with Safari...). Now I just use FireFox because they give me the option to override the default. I edit URLs far more often than typing in new ones. If I am going to a new URL, I generally type command-l or open a new tab...

The point of highlighting the URL with a single click isn't just to replace it with something else, but to copy it fast, and all kinds of users, including true power users, copy URLs much more often than edit them.

I'm sure that's the rationale, but 'true power users' likely hit meta-l to select the whole url anyhow, instead of using the mouse...
