Mr. Uptime for Firefox 3.5 released
For those of you who use our Mr. Uptime Firefox extension, we just wanted to let you know that we have updated it for Firefox 3.5.
The update was submitted to Mozilla last Friday and is pending approval, but you can already download it directly from the Mr. Uptime website. (It’s free, as it always has been.)
For those of you who don’t know what Mr. Uptime is, it’s a Firefox extension from us here at Pingdom that will tell you when a broken website is working again.

Most reasonably technical Internet users have a pretty good idea what DNS is, but what actually happens when you look up a domain name is not always so clear.
