Rated 5 out of 5 stars
Works beautifully for me.
I prefer going to IE rather than using the IE engine within Firefox, so this is great.
I miss one important feature: I'd like for Open in IE to have an option to remember sites I want to always open in IE. Some of the "fancier" IE plug-ins have this option, I don't need or want a bunch of options - Just the ability to remember which sites I always want to open in IE
For now, I'd rather use this plug-in than to install one of the more bloated ones just to get this one feature.
The most requested feature for this add-on is going to become a reality very soon. The ability to set certain sites to always open in IE will be in version 1.4, which is currently being reviewed by Mozilla testers and should be available soon!
