 Hi.

 Currently, when accessing a site Tor Browser thinks is doing canvas
 fingerprinting, it pops up a little thing asking if you'd like to allow
 it:
 1. not now (default)
 2. never for this site
 3. allow in the future

 This is excellent, and I'm super excited we're given such granular
 choices.

 I'd like an additional option, which is:
 4. Block all canvas fingerprinting, on any site, ever.

 There exists no scenario where I wish to be fingerprinted through canvas
 feature usage. I've spoken to others who feel the same.

 It makes sense to me to place it either in the about:config or the
 security slider (perhaps enabled at any setting higher than "low").
