The only time I wind up using any of IE9 is when I want to use Firefox addon IE Tab2 (FF 3.6+) to view a website. It uses the IE9 engine and opens the URL in an IE9 tab. I like this addon for several reasons.
- I don’t have to have two full Browsers open at once to view these webpages or use IE9 rather than FF as my main browser.
- I can more easily control when I use the IE9 engine then by having to open IE9 to view one page and close it when I am done with the webpage.
- I can do it on-demand for a webpage or on a saved basis for that a webpage.
- I can have it set, which I do so that the IE tab opens separately from the FF tab. This way when I close the IE tab I will still be at the website with FF.
A great addon. There are a number of similar ones on the FF Addon website but I prefer this one 
I am not sure why I can’t see the complete webpage on some websites when I am using FF. However, if I were to guess I would say that it is because of one or more of my FF addons. The addon is blocking certain content for security reasons. SISTO that by using this addon which renders the webpage in IE I could be exposing myself to some security vulnerability that I wasn’t when I viewed the webpage in FF. Of course IE9 has its own ways to check for website related Malware. Though to be honest I kind of always cross my fingers when I use the addon to render a webpage in IE9. Don’t do it very often and I haven’t noticed any security issues resulting from doing it.
