Firefox update kills security bugs, adds Mac support

Mozilla released an update to its Firefox Web browser Thursday that fixes several security flaws and, as expected, adds support for Macs with Intel processors.

The most serious bugs in Firefox could let an outsider commandeer a vulnerable computer, according to the Burning Edge, a Web site that tracks development of the open-source browser.

The vulnerabilities are fixed in version 1.5.0.2, which was released Thursday. It will be pushed out to users of Firefox 1.5 over the next two days, Mozilla, the company that oversees Firefox development, said on its Web site.

The update fixes seven vulnerabilities, Mozilla said on its Web site. Five of those are "critical," the company said. This means the flaw could be used to run malicious code and install software, requiring no user interaction beyond normal browsing, Mozilla said. Another flaw is considered to be "high" risk, which means it could be exploited to steal data. The final flaw is of "moderate risk," Mozilla said.

While Mozilla identifies seven flaws as being fixed in the new Firefox release, security monitoring company Secunia lists 21 bug fixes in the browser update. Secunia deems the issues "highly critical," one notch below its most serious ranking.

"We're identifying this as a critical release, and we're strongly recommending that everyone update as soon as possible," Mike Schroepfer, vice president of engineering at Mozilla, said in a statement. "This is one of the most stable releases we have ever delivered. It proactively addresses a wide range of security, performance and stability issues we have identified, using the very latest tools and techniques," he said.

Mozilla recommends that Firefox 1.0 users upgrade to this latest release of Firefox 1.5, it said on its Web site. The 1.5 version, released in November, includes an automated update mechanism to help people keep their systems up-to-date.

The Firefox update comes two days after Microsoft released a "critical" megapatch for the rival Internet Explorer browser, fixing 10 vulnerabilities.

In addition to security patches, Firefox includes some stability enhancements and, as expected, includes native support for Apple Computer's Macs with Intel processors. Apple released the first Macs with those chips in January, and Mozilla originally said it had scheduled a March release of Firefox for those machines.

Again....
How many times do we have to have a 'my browser is better than your browser' thread.

The story is about FF not Opera.

No it's not better.
It doesn't have the Extensions that Firefox has.

Opera even in version 8, does not support fully xmlhttp object which is necessary for web 2.0/ajax websites.

Opera blows!
Opera blows. Not as much as I.E. does, but it still blows.

Substantiate your claim with categorical evidence
We need point-by-point analysis, screenshots, stopwatch timings, and a random sampling of the population that has used BOTH browsers extensively and know how to turn on pipelining in both browsers.

So how, you want to back up your claim, or stand down and admit that you're just biased?

Got it when I woke up this morning.
had to restart the browser (I usually keep it running since one plugin tells me when I have new eMail)

a few minutes later it tells me I have to restart Firefox due to new update. Quick and easy.

while I do have some problems with it wanting to shut down every so often, IE has the same shut down problem so it is probably a problem with the website I am trying to access (same in both shutdowns)
