cool extension, however can slow your browser down massively. for example, when loading youtube in firefox, it takes 4 seconds longer with this extension installed

we need a list of all website we can ignore not only by clicking on the extensions but also on control panel of the extensions. When it run in background first time, it cause the CPU jump to 800% freezing the firefox

Please please add the ability to control the list in the extension control panel.

useful but slows down browser horrendously
