Update: There is an updated version available now that should fix this issue.

Thanks for your review. This add-on was recently ported to Firefox. There are some features that need to be handled differently, and we will continue improving the Firefox version at our leisure, since this is purely voluntary effort to make and maintain this free add-on. To limit permissions, we elected to use the built-in "pop-up". It maybe necessary to rethink this strategy in future releases since it causes user issues.
