There is no direct method to check if an add-on is installed or not. This question was also asked here before. Please see. How to check with Javascript if a Firefox Add-on / Extension is installed

If it's your own add-on then you can write some custom javascript method to try to communicate with your add-on and then display alert accordingly.

Perhaps you can find something at window.navigator.plugins?
