I’ve been using Close Button Add-on from the moment Firefox removed the feature from the browser and it works great. Recently I have noticed some pages (like Google Search or GMail) keep loading forever (the icon on the tab is spinning constantly). If I start with a fresh install of Firefox 45.0.1, there is no spinning, After installing the Add-on the icon on the tab keeps spinning. After uninstalling the Add-on the spinning disappears. I am not sure whether the problem is with the Add-on or with the browser. The author of the Add-on wrote in the Developer’s Comments: “Please email me directly with bug reports or feature requests.” But I cannot find e-mail address on the “About me” page.

How can I send a message to the author of the Close Button Add-on? Is there any bug tracking system for Add-ons (like eg. Bugzilla, JIRA)?
