Details

Steps to reproduce:

  • Enable strict tracking protection in Settings
  • In 'about:config', set 'privacy.fingerprintingProtection.overrides' to '+AllTargets,-CSSPrefersColorScheme'
  • Firefox will now present a popup in the address bar for various web sites, offering to block/allow canvas access. For me it was a gitlab issue page. I blocked canvas access permanently.
  • In Ctrl+I > Permissions, the 'Extract canvas data' entry is missing from the list. There is no UI allowing to change canvas permissions later.

Actual results:

Firefox prompts the user to block/allow canvas access, but there is no UI allowing to change permissions later. The piece of UI exists in the Firefox page info, but it is hidden.

Expected results:

Since Firefox is prompting the user to block/allow canvas access, there should be a UI allowing to alter those permissions. Notably, the 'Extract canvas data' permission entry in 'Ctrl+I > Permissions' should re-appear in the list.

The Bugbug bot thinks this bug should belong to the 'Core::Privacy: Anti-Tracking' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.
