What website or is it on multiple sites?
Have you disabled JavaScript, third-party Scripts, or cookies?
Are you using any anti-tracker or anti-ad extensions?
This seems to be an error caused by giving a page insufficient privileges to perform certain operations, or a script blocker or tracker is preventing access for a certain operation.
EDIT: just thought it worth mentioning to try clearing your cache also. Weird errors like this are sometimes caused by old cached versions of webpages or scripts and the browser isn't loading the new ones correctly.
