Clearing an Authenticated Session in Firefox
Maybe this is a widely known technique, but I must admit, it's new to me.
If you're developing on a site where you've implemented HTTP Authentication, and you're using Firefox, instead of having to exit all the Firefox sessions you have running in order to "become" another user, simply click on Tools (in the top menu), Options, Settings (under Private Data), and make sure the Authenticated Sessions checkbox is checked.
Then just go to Tools and click on Clear Private Data.
This will make the browser "forget" who you are to this site, and will trigger the username/password dialogue box the first time you try to do something on the site that requires authentication.
