CookieBlockedTracker=Request to access cookies or storage on “X” was blocked because it came from a tracker and content blocking is enabled.
What went wrong?
A request to access cookies or storage was blocked because the browser identified it as coming from a tracker and content blocking is enabled.
The permission can be changed or removed by:
- Going to Preferences > Content Blocking and either
- adding an exception with the Manage Exceptions… button
- choosing the Custom Content Blocking and unchecking the Tracker checkbox
If the blocked resource doesn't need authentication, you can fix the warning message by adding a crossorigin="anonymous" attribute to the relevant element.
