About this extension
IMPORTANT:
---------------------------------------------------------------------
Unfortunately, WebExtensions (the new API for Firefox 57+) does not have the functionality for the correct operation of this addon in Firefox.
So this addon will no longer work with the release of Firefox 57 in November 2017!
This is the inevitable change in Firefox - all Xul-addons will die out in Firefox 57

This review is for a previous version of the add-on (5.10).
