Super Ad Blocker

I am not much a fan of any of those add ons, but I am back to using IE9 after using Firefox and/or Chrome for years. After flash crash after flash crash I have lately found IE9 to be pleasantly stable. It may not be quite as fast, but fast enough. I may not stay, but for now I am here and stable.

Better browsing with IE.... you're kidding right?
Best way to get better browsing is switch to Chrome or Firefox .
Chrome already does most of that stuff without add on's (Google auto fill is one)
Chrome is decently secure (built in sandbox)
IE9 is too slow and does manage not multiple handle tabs well.
in fact I can't think of anything it does well .

What are the 5 we will lose?

Most of these 'add-ins' are available for other browsers - and most are *free* in those other browsers. There is really very little reason, apart from inertia, to actually use IE, unless you are a developer/designer.
