Ad-serving code found within both extensions
The Wall Street Journal reports (via TechSpot ) that reports from users indicated that when either extension as utilized, pop-ups and spam would spring up out of nowhere. As it turns out, both extensions had been sold to outside parties who sifted in the malicious code. Since Google doesn't check out said code after approval, users were stuck with the frustrating ads as a result.
Are you missing either one of those extensions or are you glad to see they're gone?
