несмотря на то, что обновлений не было уже давно, расширение до сих пор рабочее

This would be 5 stars, but reducing the rating as time marches on. Development was abandoned 5 years ago. Over time more sites break and show blank pages. As Firefox moves away from open source, it's what you should expect.

estensione meravigliosa e utilissima,speriamo continui a funzionare. Indispensabile per monitarare pagine in attesa di aggiornamenti,tipo concorsi o avvisi

Because of the negative reviews I see, I want to confirm that this addon is still working as intended (actually with FF 128.10.0esr). I don't experience the problems others are referring to. So, this remains one of my favourite addons, and the main reason for staying with FF. Just wished a Chromium version would exist

Un add-on toujours inégalé ... simple, efficace et gratuit !

Used to work like a charm, and for some sites it still works. But most of the time it doesn't work anymore, and you just see a blank page without the changes visible.
When you visit the Github page of this project, you see why, the add-on isn't maintained for a long time (almost 5 years) and the developer says he is not able to maintain it anymore.
Unfortunate because it was a great project, which really worked fine.

WOW! I've been searching for tool like this for a long time. Thank you!

Used to work, but just fetches empty pages...? And worse, randomly deletes the alerts that I've added with no apparent cause.

"Click this Panel" Doesn't work in Win11/FF117

Sadly, given the lack of response to any of the security related pull requests, I have to conclude this once useful extension has been abandoned. Thanks for years of usefulness.

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.
