Why does it require the "Access your data for all websites" permission?

stopped working

Works pretty well and the icon is now showing. Suggestion: Please allow disabling for specific sites (i.e. YouTube search results within Bing do not work properly).

EDIT: All of the issues have been FIXED! Arlo, you rock! Thank you so much for this great extension and useful companion to myTube!

I'm having the same problem with the last update. No icon image is shown (has been happening from a few updates back) and the following message appears when clicking the Companion button "Firefox cannot locate the file in moz-extension://c529cfb9-734c-4135-a16d-6ab585a1b209/popup.html.".

The Companion works even with these problems (the MyTube app is opened automatically), but there's no way to toogle the options if the error message appears instead.

Please take a look into this issue Arlo. The add-on is working fine on Edge.

There is no icon and when i click it it show file not found extension://67864344-5189-4c84-93d5-86b0fe3a1709/popup.html.

Excelente, muchas gracias por vuestro trabajo
