Firefox 3 issues solved

I recently upgraded (like veryone else) to Firefox 3. I't a huge improvement on OSX both UI- and speedwise. But there have been some minor issues I've had to fix:

Adblock no longer works.

The "old" adblock extension I was used to does not support Firefox 3. This extensions had issues of its own, but at least I got used to them. "Adblock Plus" seems to be the new option, which will take some getting used to but I'll manage.

Location bar behaviour when selecting.

This has been really annoying, I don't understand the sudden change. The old behaviour was that you could click on any part in the location bar and start editting, and doubleclick the url in the locationbar to select it entirely (and to replace it, for example). The new behaviour is that a single click will always select the entire URL and as I automatically start typing (i.e. replacing typo's), the entire URL is replaced. The old behaviour can be fixed in "about:config" by setting

browser.urlbar.clickSelectsAll to false and

browser.urlbar.doubleClickSelectsAll to true.
