Mozilla Foundation has reported two security flaws in Firefox web browser. If used together, they could be used to gain access to your computer. The intruders could delete your files and install new programs, so generally speaking, hackers could fully take over your computer.

Once considered a rather good replacement for Microsoft's Internet Explorer, it doesn't look that good anymore.

Mozilla has announced that they have a fix in hand, but it's still being tested at this time. For now they suggest disabling javascript of whitelist features.

Mozilla has 52 million users, but fortunately none of them have reported any problems yet.
