I use firefox more than chrome because of this extension

I like it very much. As many others say, it would be nice to be able to set a shorter than 5 minute refresh time when you have system resources to spare and want to be first to a site change. It integrates with Notification Sound (another Firefox add-on) so that it plays a sound, and you can choose a nicer one from C:\Windows\Media. It would be cool if it would also send notification emails, or integrate with a future "Notification Emails" (which does NOT exist) since the site I am following is updated at midnight and my PC is a long way from my bed. It does not let us choose a part of a page so pages that have changing adverts are fraught. Fortunately that does not apply to me. All in all, a very nice extension which provides functionality that you would have to pay for from update notification website services. Thank you Sneaky Pete.

I have been using it more than five years almost daily with no problem at all.

Toll wenn man informiert wird dass sich auf Homepage 50 von 300 mal wieder etwas tut.
Besonders gut geeignet wenn es nur alle paar Wochen
oder Monate Änderungen auf einer Homepage gibt.
Schade nur dass es in der Sidebar kein Suchfeld gibt um ein bestimmtes Updates unter 300 zu finden.
Alternativ wäre auch ein "Löschen" oder "Papierkorb Symbol" in den "Seiten Einstellungen" hilfreich.

Excelente!!

Helps me reliably to track changes of important web sites.

Good app, but the minimum autoscan time is 5 minutes, couldn't find how to make it run checks more often (1 min or less)

This was a brilliant add-on for many years. In the last days I get no updated page changes even though they have been scanned. No error message either. Have tried installing the extension on another PC with the same result.

Works like a charm!

Great plugin, much appreciated!

Полностью бесплатное приложение с открытым исходным кодом. К сожалению, в дополнении нет возможность выделить интересующую область для отслеживания изменений - как это сделано в Distill Web Monitor и Otsledit. А на нынешних сайтах со множеством динамического контента и десятками независимых блоков без это функции пользоваться приложением тяжело. очень много ложных срабатываний. Из плюсов - отсутствие ограничений на количество подписок. В отличие от упомянутых выше продуктов.

It's a very usefull extension. But I don't understand why regulary all pages disapeared and I need to import again my pages...
