Would you mind to implement that when websites attempts to access image data on a canvas, blank image data can be returned?

Issue: privacy (protection) Additional to cookies and so on, canvas imagedata is used to discover information about computers. Then Tor Browser Bundle (TBB) - Firefox ESR 24.7.0 automatically returns blank image data and shows option to switch it of and else. Would be nice to have this in Standard Firefox. Contained in TBB 3.6.3 en-us for Windows from torproject.org

Thanks, someone else raised this issue a few weeks ago: Why is FireFox allowing "Canvas Fingerprinting" to track me?

Since this forum focuses on the Firefox available today, a better place to make suggestions for changes to Firefox is the Feedback site: https://input.mozilla.org/feedback

Also, a formal request for enhancement (bug) was filed in July: Bug #1041818 – take steps to mitigate canvas fingerprinting.

It's generally not helpful to add "me too" or "hurry up" comments to bugs, but you can register on the Bugzilla site and "vote" for them to be fixed. See:

Thanks for the input-link which I used. Rest I red before plus found program lines for what I asked - both far too much for me...
