Hello,
C4C is not the same addon as before it was updated for the new firefox version.
I use your addon but I found since your last updates the main functionality has been lost. See, I like to keep track of changes and used to save both text files on my hard drive and also have an open tab on my browser that would keep updating whenever a change was found. Now, that is gone and you only get the alert the moment the change happens and if you are not there sitting in front of your pc you will not know exactly when it happened, plus you can not keep track of further changes as it was before, as you will not know when each of the changes happened. Please tell me I am wrong and somehow I am missing something or how to use the updated version of the addon. Thank you

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

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

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.vaultpit.io by going to https://addons.vaultpit.io/en-US/firefox/addon/check4change/versions/
