Is BigGo Price History Shopping Assistant safe?

Low risk

BigGo Price History Shopping Assistant accepts webpage messages that can redirect tabs or submit coupons to BigGo.

Its content script runs on every site and accepts window messages that match BigGo's fields without checking the page origin. Those messages can route the current tab through extension.biggo.com/r/ with the page URL included, or send coupon code, coupon text, and store fields to extension.biggo.com/api/shared_coupon.php using the extension's credentialed request path.
