Step 1: Clear the current browser that opens links

   On some versions of Android, this button is labeled Applications or Application manager and you may have to tap on Manage applications before the next step.

2. Tap on the All tab.

   

3. Tap on the current browser that opens links.

   This is usually the default browser, which is called "Browser" or "Internet".

4. Tap on Clear defaults to prevent this browser from opening links by default.

   If you haven't installed another browser, or you have installed another browser like Opera and set it as your default browser, then Clear defaults will be grayed out. If you have installed another browser, go back to the previous step and repeat with the default browser.

   

Step 2: Set Firefox for Android to be the default browser for opening links
