Mozilla said that users who have already upgraded to Firefox 16 can downgrade to version 15.0.1, which is not affected.

Following the report, the company has released an updated Firefox browser called 16.0.1 addressing the security glitch that could have allowed sites to find out which other web pages users had visited.
