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%

Great

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 is inconvenient because it is located at the top of the page each time it is updated.
I want you to keep the scrolled position.

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

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

It literally doesn't do anything. I set a time interval and then it still just says "OFF".

простое и приятное дополнение. работает как надо!

Works, but the UI is pretty awkward.

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.

I needed another auto-reloader, so I decided to give this a try, even though in the description it sounded a not so good idea (reloading based on URL, instead of tab id.) It has no [Apply] button or anything, so I was never sure the period was set or the add-on was active for the tab/URL (even though the period set reappeared when I reopened its pop-up). Anyway, nothing ever happened, no reloading, no nothing...

Works fine for me.

Was alright, kinda clunky interface, but it's stopped recognizing what tab I'm on and only ever sees one tab regardless of what I click on.

When it worked it was great, but those days are gone :/
