Attention: Firefox 57 will drop all support for classic Firefox browser add-ons in honor of the new WebExtensions add-on model in November 2017. This add-on is among the thousands of other Firefox add-ons that will be left out and cannot be converted to the new add-on model. If you are unhappy about this change let Mozilla know about it! Thank you for all the support and enjoy my add-on as long as it works.
