a timocracy of one

Ever get tired of the first result in your address bar dropdown for a given URL being a typo that goes to a 404? Well, you can delete just that entry, after all.

In Firefox, if you want to delete an individual entry from the History, just highlight it (either in the History sidebar or in the address bar drop-down) and press Shift+Delete.

I finally found an extension that lets me use Firefox for testing that I would previously had to use curl for, namely submitting text/xml only requests (for testing REST APIs, for example) or similar. I thought ModifyHeaders would do the trick, but I never really got that working. But TamperData is exactly what I wanted.
