If you don't like Internet Explorer, and would rather use Firefox, some sites make it hard for you.
Sometimes, they just nag you with warnings. Other times they just plain refuse to load in your
browser, or even try to warn you your operating system is wrong...in Spanish!
Here's a handy add-on to work you right around these artificial barriers.
Go to addons.mozilla.org and search for user agent switcher. Add the plug-in to Firefox and restart
Now, when you come upon a naggy site like this one,
Go to tools, select User agent switcher, and select the browser you need to pretend to be, in this case
Reload the page and the prejudice ends. You can use it on many sites to log-in to your classes or pay
your bill. It will even fool Mozilla.org into insulting you for using IE. That's how good it is.
Do be aware, sometimes the reason they warn you to use a certain browser is because their crappy
site BREAKS in every other browser, so the user agent won't help you in those situations.
But for a lot of sites, you'll be able to use them just as if you had Internet Explorer running in Windows.
Hope that makes your web browsing easier. I'm Tom Merritt, CNET.com.
