Great, does its work.

It used to work well. Now keep noticing there is change while there's not.

Says there is a change when there is no change

Does not work with Firefox 57 - there is no Settings available, no customization.

The new version was on the beginning somehow annoying with the pop-up. But I get used to it. The addon is nearly perfect for me. And the pop-up can be removed if you click "Hide this dialog".

changed the icon of one of my bookmarks and will not let it change back to the default after removing the addon

How can I get rid of that stupid popup - so silly. Typical for see how fit I am with the system - but not see what the user needs!

Used to be great, but since v2, many more clicks are required to start a scan and, even worse, the Check4Change window now blocks the browser window such that it can't be used. This is a major regression.

It seems many other people are affected. You can install the old version right here at addons.mozilla.org by going to https://addons.mozilla.org/en-US/firefox/addon/check4change/versions/

PLEASE change the interface to the way it was before 2.0! The new version blocks the window and it we can't see it. Also, it does not seem to be functioning well, and every time I want to monitor something I need to create a new "job". Before, with the contextual menu, my last used setting was already there, it was simple and fast. This version now takes a lot of clicks. This is a major step-back.

I love this extension. I do some online work that only gets posted up sporadically. This extension means that I can get on with other things without missing out on jobs. It can be customised to exactly the amount of time I need which is better than other extensions that I looked at.

the older version is so much better, in the tab, you could see, that anything is working, and now the window on the checking side is not to hide :(
