"Never allow" doesn't work in the canvas popup
Dear Tor Developer,
I've visited "Jesse's Cafe Americain" using Tor browser at this address http://jessescrossroadscafe.blogspot.com/ for several years and always get the warning from Tor that this website "attempted to access image data on a canvas" (an ID security breach).
At the bottom of the warning box there is a selection button allowing me to choose to "allow" this behavior or to "never allow" this behavior. I always choose "never allow" and that has always worked until my recent upgrade to Tor 2.3.25-14. Now, the warning still appears, the selection box still appears with both options, but the "never allow" option can't actually be activated. When I click "never allow" the "allow" default doesn't change and the warning box disappears with the "allow" option unchanged.
As part of the fix, I suggest you change the warning box option to default on "never allow" and force users to select "allow" at their own risk. Thank you for all you do,
- L. H. Melvin
