Firefox 1.0.1, the name for the updated version of the increasingly popular web browser, includes a patched vulnerability in Internationalized Domain Names (IDN) that previously allowed production of spoof websites.
"Regular security updates are essential for maintaining a safe browsing experience for our users," said Chris Hofmann, director of engineering at Mozilla.
The vulnerability allows redirection of websites to spoofed creations, even if the URL appears to correct.
According to the Mozilla Foundation, the open source group who own and operate Firefox, the update also fixes a number of other bugs.
The Firefox browser recently surpassed 25 million updates, and some analysts are suggesting it's a genuine challenge to Microsoft's Internet Explorer in terms of browser hegemony. The number of downloads is all the more remarkable in that it was achieved in under 100 days.
"Twenty five million Firefox downloads is a significant achievement, and we see that number continuing to grow," said Mitchell Baker, president of the Mozilla Foundation.
Mozilla's reputation was further enhanced this month when it became the recipient of the Editor in Chief award (SC's highest accolade) at the SC Awards in San Francisco.
