User reviews
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.
