In my laptop I was using internet explorer 8 and I was not having any problem with that. Before some days I have installed Mozilla Firefox in my laptop and I like that browser very much because in Mozilla Firefox we can get lots of add-ons which can be very useful for me but after updating the Firefox to latest version It has started giving me one issue. Now whenever I open the Add-ons option at that time my browser freezes for 5 to 10 seconds.
