I use both Nightly and regular Firefox. The Wikibuy addon works fine in regular Firefox but gets locked up in Nighthly. I have tried uninstalling and reinstalling the add on and I have confirmed that Nightly is up to date (63.0a1 (2018-07-01) (64-bit)). When I am on a web page the pop up will show in the upper right corner but it will not allow me to click on the link or to use the X to close the pop up. It's an issue because then I cannot access anything in the upper corner of the webpage. I clicked the debug button in addons but I admit that I'm lost when it comes to this. Here is part of what it said. Could not map contract ID '@mozilla.org/fxaccounts/push;1' to CID {1b7db999-2ecd-4abf-bb95-a726896798ca} because no implementation of the CID is registered. components.manifest:163 Loading failed for the <script> with source “moz-extension://80dd134c-0938-6149-b524-7bac4b6342c7/content/browser/chrome/js/MP.js”. bg.html:3 The character encoding of the HTML document was not declared.
