One thing that has always bugged me about Flex Builder (or more specifically Eclipse) is that when you click the Run/Debug/Build button (or F11/ctrl-11) your project is always opened up in a new browser tab. It doesn’t take long until you realize that you have 20 tabs open – or at least in my workflow it happens!
So last night I built a Firefox extension that I have been wanting to make for a while. It’s called Prevent Duplicate Tabs, and ensures that only the most recent tab of a given url is open at any one time. After its installed, you will notice that there is a menu item in the Tools menu called “Prevent Duplicate Tabs”. By default it is checked, and if you want to turn the extension off, you can simple toggle the menu item.
This is my first ever Firefox extension. It was a bit of a pain to develop, and I now have even greater appreciation for the Flex documentation ;-)
