Is dataslayer safe?

Low risk

dataslayer lets any website turn off its analytics-request blocking rule through a page message.

The extension forwards page messages whose type starts with dataslayer to its background script, which accepts a dataslayer_loadsettings message with blockTags set to false and removes the blocking rule. Once removed, analytics requests that dataslayer normally redirects for Google Analytics, DoubleClick, and Adobe analytics can go through with their URL, referrer, and headers.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.
