Internet Explorer 8 is here

[Und3ertak3r]

usually when i open microsoft site using ie7 it hang the whole system

this is not the case with firefox three
firefox also had a plenty of pluging which are not available in ie
are there any majour security isue for which some of u are not recomding firefox

Only time I have seen a Hang with IE6 or 7 on an MS site has been when I am looking at a multi malware infection.. latest was SDBOT..
So you must be having a hell of a time if you do a manual update.. is the auto update working? (well at least notifying you of available updates)

FF 2 or 3 with out a good script blocking addon is like hanging a sign around your neck.. "ass for any takers"
BTW.. FF3 is my default browser on this machine

And there are plugins available for IE7..some are free..
And MAny here are NOT IE fanboys.. we will call a spade a spade.. in your situation your blaming the car for the flat tyre not the hole in the tyre.

And we are not recommending IE.. we are just pointing out that from your description.. your installation COULD have a problem.. not a innate issue with IE..
