How to make firefox plugin compatible with FF 3.6.13
Id like to install this plugin for Firebug, but it says that its incompatible with FF 3.6.13. How to make it compatible(I have never done any FF development, so any pointers would be great)
Simply use the add-in Nightly Tester Tools. With it you can overwrite the state of incompatibility.
Here it is explained how to use it.
