A week after two major bugs were discovered in the browser, they have been fixed. That’s quick action! 1.0.4 was released a few days ago, but I didn’t know that it took care of these bugs.
“The first flaw allows a third party to add program extensions to a Firefox user’s software, which ordinarily must be done at the Firefox update Web site. The second flaw takes control of Firefox to remotely navigate to previous Web sites. Taken together, an unscrupulous hacker can steal personal and financial information from the user.”
Read about it here, and if you see the red arrow in the corner of your FF browser, click it to update to 1.0.4.
