Единственное нормальное расширение в своем роде

The best!

Please consider adding an UI element for adding/removing the site from the whitelist without having to manually edit the string in the settings. This UI should appear in the popup menu when the extension icon is clicked. This extension would be much more usable with this.

UPDATE: This is great! As I mentioned on Github, I missed this because I'm not used to paying close attention to the icons in the address bar often since I'm using Tridactyl. I've updated my rating accordingly.

The addon works perfectly. I tested all extensions for blocking canvas and this one definitely does the best job.

Hello, excellent program, for when a version for the Opera browser ??????

It gets the job done.
Didn't even know I need it until a web page started to abuse canvas to shove ads in your face

A must have privacy extension for everyone!

Great stuff. I think this should be a "featured extension" in the pivacy and security category.

Nice, but the toolbar icon changes color sometimes (red/green). What do the different colors mean?
Green = I'm save, red = I'm not protected? And what do I have to do for it to protect me again?

I tested this addon with the Panopticlick test from the EFF, and when I check the 'full results' it shows that the hash values are changed every time I have the addon enabled. So I guess it's basically ruining it for people who use these values to track you.

It is great, but it'd be much better if the Mozilla Add-ons link embedded in it was language-agnostic. Currently, it is to the German version of the site.

You are very hard working person :)
