Nice, simple, does the job Rated 4 out of 5 stars

I like add-ons that don't over think things, and this one suits my needs fine.
One question though, is there an option to launch items as a new tab in IE if it is already open? I have multiple things that I sometimes need to run at once that need IE and I launch them from a page in Firefox. If possible, I'd rather not have multiple instances of IE get launched in the process.

This review is for a previous version of the add-on (1.3.1-signed.1-signed).
