I opened Firefox today and had a new icon at the top right:

Ebay Highlighter AutoInstall?

I didn’t install the highlighter and I never saw any confirmation windows asking for permission to install it.  Has anyone else had the Ebay Highlighter Auto Install / Install Itself / Magically appear?  I had to Google to find out what it was, it “lets you highlight different products in Firefox or Internet Explorer and compare the pricing of those products on eBay.”  – Tech Crunch

The last thing I need is additional addons/plugins installing themselves in Firefox!  Anybody else get a confirmation or dialog?  Maybe I’m just special?
