Allow user to completely disable canvas content and related warning popup from a checkbox in TorButton's "Privacy Settings"

Canvas-based fingerprinting is a potent threat to anonymity. I believe it does not make sense to have it potentially enabled (following a popup dialog) at elevated Security Slider settings, and even with the Security Slider on "High," and probably also on Medium-High, Medium, and potentially Medium-Low.

Fingerprintable canvas content (and its related popup) should be completely disabled when the Security Slider is at one of these elevated settings, and it should be transparent to the user. It may make sense to still present the icon in the address bar so that it can be enabled manually, on a per-site or per-page basis, if a user needs this feature.

Thank you all so much.

It's a security slider and no privacy slider. And that is on purpose. Mixing both things is not a good idea as this makes communicating the goal of the slider harder and analysis of its effect as well.

The rationale here is: "present the icon in the address bar so that it can be enabled manually, on a per-site or per-page basis, if a user needs this feature." instead of annoying popup.

Thanks gk, understood. In that case, I believe that such a toggle is absolutely appropriate in the dialog area just above the Security Slider in "Privacy & Security Settings..." as an additional checkbox within the "Privacy Settings" area.

I propose that the box's description should read "Disable HTML5 Canvas content."

Further comments welcome.
