TBB gives a privacy warning concerning canvas. Is this an addon we're using? What triggers the warning? TBB bug?
From the console log:
Blocked http://kkkkkkkkkk63ava6.onion/blog/ in page http://kkkkkkkkkk63ava6.onion/blog/ from extracting canvas data. http://kkkkkkkkkk63ava6.onion/blog/:51.
Line 51 is related to Wordpress' emoji-rendering code, which is done with the HTML5 canvas.
Following the advice outlined on http://www.denisbouquet.com/remove-wordpress-emoji-code/, this prompt no longer appears.
Of course, we no longer have the Wordpress emojis, but that may be a good thing depending on how you feel about them :)
