Rated 5 out of 5 stars

Nimbus Screen Capture, is just what I need to simply take necessary screenshots of websites.
And for those who have reviewed before me a grumbled about the loss of the copy function - read this:
"Current versions of Google Chrome and Mozilla Firefox prevent apps from copying pictures to clipboard."
A simple workaround is that you can simply right-click on the picture you see on the screen and select "Copy image".

This review is for a previous version of the add-on (12.4.1).
