I'm not sure about this add-on (i suppose it works fine) , but my personal favourite is "IE Tab Plus" .
This add-on simply adds a button , so 1 click and it changes the page in FireFox into a page like IE works .
This all works in FireFox itself , so no need to open IE itself since i only use for pages in the wrong format for FireFox .
Anyway , keep it up , and maybe add a hotkey for a 1-click experience like "IE Tab Plus" ......
