FireFox users often run into websites that have require Internet Explorer for accurate rendering of the page. Typically this is the case for complex web applications built in ASP.NET or Microsoft sites such as Windows Update. This annoyance has required FireFox users to open IE specifically for these sites, well at least until you come across the IE Tab FireFox extension. Installing this extension allows you to program the extension to open Internet Explorer in a new tab directly within FireFox for sites that you choose or to render the current tab with IE.
Anybody who has used FireFox realizes how helpful this is. It has now become my favorite FireFox extension and I thank the Joel on Software blog for introducing me to the extension.
What are some of your favorite FireFox extensions?
