Report an issue

Include the browser, the rule settings, the action you took, and the result you expected. A small made-up example helps reproduce the problem. Do not send private names, customer lists, credentials or confidential files.

For example: “A contains 00123 and 123. B contains 123. With default rules, I expected only 00123 in Only in A.”

You can also suggest an improvement or ask about the matching rules. There is no guaranteed response time.
