Add does exactly what it says it does. Mark the part of a webpage you want to monitor, and it reliably informs you of updates. Good UI too.

This works so better with descent internet connection. Alerts are so accurate and hardly any notification missed on my use. Also it can load it in background by disabling JavaScript.
Perfect so far !

Incredibly useful. It's an extension I'd hate to be without as I have a lot of sites I need to keep an eye on and this does the job beautifully.

I'm not a web teccy but this was super easy to use. Unlike several others I tried the free version just worked with no cloud-dependent sign up issues. You can go down to as little as a 5-second interval running monitors on local device. Setup is easy point and click. Lots of ways to get notified - , popup, sound, email, SMS, push (last 2 require subscription but not expensive)

Brilliant so far, makes website monitoring easy

I am very helpful because I can get various information updates quickly.

Fantastic addon - has made my life easier

I have tried over 15 different addons to monitor website and this one blows the others out of the water!

What a fantastic, easy to run monitoring app. This just simplifies everything.

Add-on allows me to check and manage my monitored website easily. Best website change checker.

Fantastic tool and solid extension that does the job in an efficient way . 5/5 STARS : )

Distill is a life saver. Literally, I have my life back since I don't have to sit and refresh a site for hours on end waiting for products to release. Now I get an email/sms notification and I'm good to go.

Perfect, it was very useful!

I needed an extension to monitor a tracking page and get update immediately after a change. Distill is the perfect extension to do it! Completely efficient, not cpu/ram eating, super quick and allows to be notified in many different ways! There's no doubt, this is the best extension about this topic, and of course one of the most useful on the whole firefox market!

great tool for trying to find sold out performances
