The new Safari version, called the "Content Blocking Safari Extensions" will be released in the fall, the company said.
The change comes as Apple believes that "privacy and security are among its greatest differentiators" against other competitors, like Google (GOOGL)'s Android mobile platform, the Financial Times reports.
"Blocking gives your extensions a fast and efficient way to block cookies, images, resources, pop-ups, and other content," Apple said in documentation for developers, CNBC.com added.
However, as revenues from mobile ads rise, this change is striking fear into advertisers, who look to the mobile platform to generate revenue, according to CNBC.com.
Separately, TheStreet Ratings team rates APPLE INC as a Buy with a ratings score of A. TheStreet Ratings Team has this to say about their recommendation:
"We rate APPLE INC (AAPL) a BUY. This is based on the convergence of positive investment measures, which should help this stock outperform the majority of stocks that we rate. The company's strengths can be seen in multiple areas, such as its solid stock price performance, impressive record of earnings per share growth, compelling growth in net income, robust revenue growth and notable return on equity. Although the company may harbor some minor weaknesses, we feel they are unlikely to have a significant impact on results."
