Excellent!

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..

I try to setup refresh on one tab, but it only gets activated on a different tab in an *other* window! Needs some more work...

It would be great if it had a sound alarm when change occurred.

Can be better, unfortunately..

When activated goes on error.
Tested on the latest Firefox Developer

Ótimo app!!! Muito prático e direto ao ponto, funciona 100%

UI is wrong when I put icon on the menu.
