There are many websites that were designed only for Internet Explorer and do not run properly on Mozilla Firefox. But if you love Firefox as I do and don’t feel like going back to IE to view these sites, here is the solution.
Download and install the IE-Tab Plugin. You can browse IE-only type of websites right from your Firefox. Just click the IE-tab button and switch to IE from within your Firefox browser.
This has another advantage for webmasters and developers, as you can easily see how your web page will be displayed in IE in a single click. You can then switch back to Firefox.
