By only allowing Mobile Safari as the default browser in iOS, Apple (NASDAQ:AAPL) has given itself a major advantage in the mobile browser market. The company permits third-party alternatives, but they can't be used as a default. That convenience factor goes a long way, particularly when viewing content from third-party apps.

Google (NASDAQ:GOOGL) recently said it would begin offering developer tools that allow app developers to send content directly to its rival Chrome browser on iOS, which could undermine Apple's own browser. However, Apple still has other ways to give Mobile Safari a leg up, like the Nitro JavaScript engine that it doesn't allow third-party developers to tap into.

In the video below, Fool contributor Evan Niu, CFA, explains how the move could help Google make a dent in Apple's mobile browser share.
