Great tool to monitor web pages or part of it!
Easy to use and configure.

Great job done here.

A wonderful addon!

This is a great addon. Keeps track of items I am looking for on ANY website I want. It's been a Godsend and I just don't know what I'd do without it. Amazing support as well. Always replies quickly to any questions with concise answers. Can't wait until my business grows so I can upgrade to the Flex plan. Thanks a million!!!!!

Amazing. Does what other web sites charge for and do badly. They offer multiple/customization intervals for checking and can setup email alerts for free. Great app, works like a charm and easy to use.

请为“Open Page In Tab (for local monitor)”添加一个后台打开的选项。

very fast and clear to monitor web changes. I hope the alarm function would be enhanced. Thank you!

Muito boa! Fácil de usar.

Your're gonna save a lot of time for a ridiculous price

One of my favorite firefox extensions! Thanks for FF57 support. I also use it to monitor local files e.g. "file:///B:/Backup/backup.log", but this new version has problem with monitoring these files, it will be great to support these urls too, thanks.
Edit: maybe access to filesystem from extensions is not allowed in new FF, I have added backup folder into apache virtual-host settings and now I can monitor backup logs too

Best web monitor out there! Very easy to use and error free. Fast tech support also. They have answered all my questions.

Have only noticed minor issues, so far so good. Thanks for the update!

Such a great addon. Props to the dev for working out this new one.

Hope it more stable not abuse the resource.

This is the best extension for monitoring websites, or specific parts of websites, for changes at an interval specified by you. Has an email support.

when installing I get an error that says it appears to be corrupt
