In their blogs, the two groups lambasted Mozilla, predicting dire consequences, including the shuttering of small businesses and small websites, fewer choices for online users, and more ads in Firefox.
"If Mozilla follows through on its plan ... the disruption will disenfranchise every single Internet user," said Randall Rothenberg, president and CEO of the IAB, in his post. "All of us will lose the freedom to choose our own online experiences; we will lose the opportunity to monitor and protect our privacy; and we will lose the chance to benefit from independent sites ... because thousands of small businesses that make up the diversity of content and services online will be forced to close their doors."
