Could you retest in safe-mode? http://support.mozilla.com/en-US/kb/Safe+Mode
If it also happens in safe-mode, could you give a link to a page where this happens?

I can confirm this does happen in safe mode. I can always reproduce this on a uk paper's website (thesun.co.uk) presumably because of the way their site is written.

I have picked an article at random that has a picture that opens a new window.

If you click the large picture, close the popup, and then immediately use the arrow keys to scroll the error will happen.

Thanks

Ok thank you, I can indeed reproduce this on Windows XP.
It worked for the last time correctly before the notificationbar was broken (Bug 306210). And when this was fixed (Bug 304462) this bug appeared for the first time.

Well, the page does have some strange javascript code.
If you focus the big image in that page (click or if you don't want to open a 
new window, just use tab few times), the focus is in under an <a> element, which
has event listener for keypress events. And regardless of the key you press, 
script is trying to open a new window.
So for example (if you don't have 'search for text when I start typing' activated) pressing 'a' will try to open a new window.

But we do have some special code for up/down keys in popup blocking code.
That was added there long time ago, in bug 252326.
Seems like up/down makes the action to be 'openControlled'

Sounds like the site is attempting to open popups when keys are pressed etc, and we're blocking them. Something apparently did change if this didn't use to happen, but whether that's due to a bug we fixed or introduced is not clear. Not going to block the release on figuring that out.
