Hi, This forum is intended to help users with Mozilla products, such as Firefox, while your question seems to be related to a third-party extension. As a moderator, I'm going to mark this thread as off-topic and lock the thread since it is not a subject covered in the support forum. Please see [[Mozilla Support rules and guidelines]]. To get help with an extension, head to its support website from its page on addons.mozilla.org.
