Unable to filter out errors

We’re receiving errors from what seems to be from some Kaspersky browser plugin. Our configuration for raven-js is supposed to be filtering those out. The errors are coming from this script:

https://gc.kis.v2.scr.kaspersky-labs.com/5BDD56F8-A99B-1549-B8F7-952C5B339D07/main.js

…and our configuration looks like this:

{ ignoreUrls: [ /kaspersky-labs.com/ ] }

Any reason why this is not suppressing these annoying not-ours errors?

Never mind, I think this is operator error where our configuration isn’t being used correctly.

Turning on your Inbound Filters (specifically browser extensions) should also filter out kaspersky-labs
