The discovery of a critical bug, which the company said \u201ccould allow a malicious site to potentially determine which websites users have visited and have access to the URL or URL parameters,\u201d prompted Mozilla to pull <a href=\"https:\/\/www.intego.com\/mac-security-blog\/mozilla-foundation-releases-firefox-16\/\">Firefox 16<\/a> from distribution on Wednesday while working to resolve the issue.<\/p>\n<p>Although the vulnerability is now fixed in Firefox 16.0.1, security researcher Gareth Heyes missed out on a $3,000 bug bounty after <a href=\"http:\/\/www.thespanner.co.uk\/2012\/10\/10\/firefox-knows-what-your-friends-did-last-summer\/\" target=\"_blank\">blogging about the Firefox 16 only symptom<\/a> before Mozilla was able to fix it.
