The extension I created will not install for testing. It always says not compatible with Firefox 23.0.1.

I am in the process of porting an extension from Chrome to Firefox. The extension is called The Unofficial Openstudy App and it can be found on the Chrome Web Store. I have got everything ready for testing but it will not install the XPI file. It only says "not compatible with Firefox 23.0.1." I have tried modifying the minversion and maxversion in the install.rdf file but it DOES NOT WORK. Why is this?

What are your minversion and maxversion? Unless you set strict version numbering, Firefox generally should allow you to install extensions even if Firefox has passed the maxversion.
