Thank u for making this addon, it works fine but give a configuration when the tab is background to refresh is better. Mostly, the tab is no need to refresh when u working with it. Thank u again if u can improve it..

Please, add context RMB-menu - for pages and tabs, as alternative to the button-menu.

p.s. Do you have a github page ? )

Works great in Firefox 57 (Developer Edition).

My only wish is that I could type a refresh interval into the interface instead of having to use the up and down arrows.

Nice add-on if you use a single browser window. However, if you detach a tab from the main browser window this plugin no longer correctly identifies the url of the detached tab. Other than that, seems to work fine.
