Found this useful tip on how to add a ping shortcut to your Firefox address bar over at Lifehacker. I love its simplicity. Pinging servers is a great way of finding out if they are currently up and running. The time it takes to receive a response is measured in milliseconds and a timeout is returned if it takes to long.

When you click on a file Firefox determines if there is a plugin that can handle the file type or if there is a so called download action defined. Download actions are user defined actions that come into effect when the box “Do this automatically for files like this from now on” is checked in Firefox during a file download.

Did you ever feel that some of the right-click and menu options are completely useless ? I know of several that I’m never using, want some examples ? Work Offline in the File menu, Send Link in the right-click menu or For Internet Explorer Users in the Help menu. Removing entries increases the usability because it makes it easier to locate the right options putting them more into focus.

The terminology used by the Mozilla team is sometimes a little bit confusing. Could you for instance define the differences between add-ons, extensions and plugins ? The first two and the latter are different which is easy to explain. Plugins are installed by third-party applications while add-ons and extensions are installed by the user himself.

I have been encountering a warning in Firefox lately which told the that a script on the current website was unresponsive asking me if I wanted to stop or continue. That’s a pretty vague warning and I was puzzled at first about the cause of it. The strange thing was that the website seemed to have loaded completely and that the warning was displayed despite of this.
