since upgradeing to firefox 12, i cannot close tabs - the x in the tab does not work - there is also no option in the right click menu to "close tab" - so i am having to use "control f4" instead; and the setting i had for yahoo toolbar for no text next to the buttons is not working. also since version 11 there is no option in the right click menu for "open page in ie" Is there any way of fixing these problems please?
