Should i upgrade Internet Explorer 7 to Internet Explorer 8?
IE8 is more secure. Having said that, the choice should be simple. 
thank you.
how do i use tabs on internet explorer 8? Something comes up that says what do you want to do next when i open a new tab.
you just type in the website correct?
Since Internet Explorer 8 has just been released in its final form in March, and as usual there are complaints about problems with it, wouldn’t it be a good idea to wait a little while for these problems to be resolved, and websites to get up to speed? I do know that it is supposed to be more secure and would like that. I always upgrade Firefox when they come out with a new number, but they aren’t usually this radical and come in smaller increments.

IE8 uses more RAM so it takes a bit longer to start than IE7 and each tab uses its own address space so it uses more RAM but this provides isolation for each session.
The address bar works the same way as IE7 so just type the URL there and depress Enter.
