Firefox won’t “Search”

My Firefox 4.0.1 won’t search when I fill something (anything – no prefference 😉 and hit Search.

Why? Don’t know yet. But I have a workaround:

Open your prefered (search) page – mine is google – go to Tools – Options – General and use Use current page button.
Your next search on your home page will work flawlessly.

I like Firefox, and I like even more Firefox 4, but this is a glitch they’ll fix pretty soon, so I don’t really bother.
This issue will not show up on all computers, but many of them will show this behaviour.

For those that use Firefox 4 with the new Firefox button (menu), press ALT to reach the Tools menu.
