FF 58 HTML5 Canvas Global Block #345

Open collinbarrett opened 6 years ago

collinbarrett commented 6 years ago

FF 58 now supports HTML5 canvas image blocking. It provides a per-site permission pop-up. It'd be great if there was a way for user.js to enable this block setting globally.

It's already enabled.

When you set privacy.resistFingerprinting to true it enables canvas blocking.

Right, thanks, but I was wondering if there was a setting to essentially "Don't Allow" globally for all sites, rather than answering the prompt on each site.

Granted, I haven't combed through that entire bugzilla thread yet, so maybe there is discussion around that already. Will read that later and update. Thanks for sharing that link.

If you use the relaxed branch, you'll have an option to "Always remember my decision". Don't know if there's a global setting, but I'll look into it.

FYI: 1429865

I would assume it will be similar to all the other default permissions landed in 58: so something like permissions.default.canvas or since its tied to privacy.resistFingerprinting maybe privacy.permissions.default.canvas .. with 0=always ask, 1=allow, 2=block
