Maybe you, too, are forced to use a web app that doesn’t support Firefox? At my work, we use Salesnet.com. Says salesnet.com’s login help screen “The application supports Internet Explorer 5.0, 5.5, 6.x, and 7.x. You cannot login with any other browser.”
That’s pretty inconvenient, particularly because it doesn’t even do a very good job in IE 7.0. It keeps complaining about the pop-up blocker being on, when the pop-up blocker is clearly off. Annoying.
Enough of this silliness! I installed the User Agent Switcher Firefox extension, restarted firefox, instructed the extension to identify my browser as IE 6.0 and HUZZAH! I could log into salesnet.com and do my work.
Nice job dumb Salesnet.com people.
