characters in it - the active tab becomes unfunctional: it grays out and you
cannot close it.
On my actual build (Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8b2)

2. Copy and paste the above link.
3. Try to navigate ... well you can't !!

Actual Results:

OK, I got it: it occurs only when AdBlock extension is enabled.

As a "bonus", when the bug has occured, I cannot close the window from the
File/Quit option, I have to click on the right upper corner.

In my opinion, there are some exploitable flaws in there and they are just a
little highlighted by this bug.

Please report the bug to the AdBlock developers.

->INVALID

p.s. If you can demonstrate the "exploitable flaws" with extensions disabled
then please reopen the bug.
