There is a vulnerable bug in old firefox which can result in crippling attack.So update as soon as possibel .
^Just a tip from me ;)

Firefox is too bugy right from beginning.I like some of its extensions.But still i use Internet Explorere 6.

Would you like to tell what exactly the bug does.
It's quite fine for me no bug .

Marima there could be lot of bugs including bugs for displaying website in right order etc.

I am using 1.5.0.1 ;)
