used to be great. not now. new version deleted all my scan pages. no way to recover. no help available. do not use. do not support.

This is a great add-on. The only thing I would ask is the chance to put the sidebar list in alphabetical order rather than newest added first. If you end up with a lot of sites that you are trying to monitor, you may end up adding the same site twice and not be able to delete the copy. PLEASE!

I can't get this to work. Most of the time I click the icon, I get a blank drop down window.

Lack of features. Can't choose a specified item of web-page by DOM. Can't set delay in seconds between web-page checks. Can't specify random delay also. Etc...

That's quite perfect, only missing thing is higher checking frequency.
What about introducing checking frequency up to 5s or at least 30s?

Thanks Pete!

estou iniciando uso agora...?

Please, make so that this addon make a simple request (GET) to some user defined URL to trigger any user`s procedure (when a webpage is updated).

Works as advertised. Sometimes sites with very active side-bars can fool it, so the only feature I'd add is to be able to "train" it what sections of a web page it should care about.
