Rated 4 out of 5 stars

Works most of the time, but sometimes after I select "Allow requests from *.[website]" (I don't know if this is the exact phrasing in English because I'm using FF with German language settings), the site isn't reloaded but only an empty tab is shown and the history of the tab is empty, so I have to search for the website's URL in the browser history.

This review is for a previous version of the add-on (1.0.beta11.1). 

Thank you for your report. To help fixing the bug, please tell me the exact steps how to reproduce it, either on github or via email. Thanks.
