IE doesn't install add-ons like these in the same way.

In fact I know that the AdBlockPlus developers decided never to develop their ABP add-on for IE. Whether that "never" means never, I don't know.

I know WOT has a version for IE as I have it myself, but you need to visit these sites, the ones who develop the add-ons and not the Mozilla add-on web site, with IE itself to see if they have versions for IE.

By visiting the sites in IE the web page recognises which browser you are using, and so gives the appropriate information, more often than not.

I hope that helps.
