Not much to tell. It just plain doesn't work. I installed the newest version today and nothing - it's like it isn't even there. Using Firefox 53.0.3 (I cannot upgrade FF because of the new way they treat plugins and addons - most of my plugins/addons don't work at all under Firefox's new setup.).

Edit in response to developer reply: Thanks for your reply, but I'm not going to lose 20+ plugins just for one. 57+ kills almost all my other plugins. I sure do wish I had access to prior versions of your plugin.
