Jimmy M. writes "A new vulnerability has been announced in Internet Explorer, also affecting XP SP2, which can very easily be exploited by a malicious web site to completely spoof the address bar. The vulnerability is very similar to another vulnerability disclosed just about a year ago called the '%00' vulnerability, which also was widely exploited by phishers. A demonstration is also available."

In the URL bar type about:config and then filter for "ntlm". In the network.automatic-ntlm-auth.trusted-uris just put a comma separated list of servers you want Firefox to send your NTLM to. For example, double click network.automatic-ntlm-auth.trusted-uris and put in foo.com,bar.com,slashdot.org
The only thing I wish Firefox did was to allow a wild card domain name like *.mycompany.com. My network.automatic-ntlm-auth.trusted-uris entry has gotten pretty long at work : (

Negatively advertising about your competitor (talking about why their product is bad, rather then why yours is good) is bad no matter what position in the market you're in. Instead of saying you're the underdog but people should try you out, you're saying your competitor is bad, so you're all that's left. People aren't interested in leftovers and those winning by default. If Firefox wants to successfully advertise, it should be talking about "faster browsing" without actually mentioning what it is being compared to, let alone naming Microsoft or IE.
And that boys and girls is why the basement dwelling me too fanatics who crowd around OSS are doing far more harm to OSS adoption then good. No business is going to suddenly switch to open source as long as "OMG M$ IS TEH SUX0RS!!!!!!!" is the message crowding out any intelligent and level headed promotion of true technical and cost superiority.

Of course we'll survive. It's just the internet. But, many of us are software professionals. We care so much about this we decided to make a career of this. We care so much about this we're willing to give away our ideas as open source projects, just to share them with the world. Forgive us if we care passionately about this, and think that basic things like browsers should not have security hole after security hole till we wonder if it will ever stop.
And, it's not even too much of a stretch. Enough people get screwed with identity theft, and the trust of the system falls apart and it ceases to be a method that many of us earn a living with. If one of the largest companies in the world can't even fix their browser, with all the resources of an almost monopoly on the market and stock options to hire every CS post graduate student on the planet -- a technology that went through its basic definition years ago -- it puts into question the entire value of software professionals.

But I can't name any other profession in which it is possible to profitably release product after product while being completely incompetent to produce. [Ignore management; it's not their job to produce.] You don't have to be a good programmer to succeed; you only have to look good. I was taught programming by a college professor who believed--seriously believed--that having five consecutive GOTO statements was a valid result of "structured programming"! I've seen countless examples (as have most people here) of bad programming. I decided years ago that anybody who actually trusts a computer is insane. I rely on computer records; I have no choice unless I want to live in a hovel in the woods and keep all my money in a mason jar. But I don't trust them, and I never will; I've known too doggone many programmers.
Just yesterday I had a lengthy discussion with my boss (the company owner) about why IE (and Windows in general) is so weak. With all the resources of an almost monopoly on the market, you said--that is exactly the problem. Microsoft has little motivation to do more than keep hot-patching the holes in IE and Windows instead of tearing up the whole street and laying a solid foundation. In the 1960's and 1970's, IBM stayed on top of the mainframe market despite having one of the worst OS's around, because they had the most ruthlessly effective body of marketeers anybody'd ever seen; only the virtual disappearance of the mainframe market took IBM from the top. As long as Microsoft's marketeering position stays strong, MS software will stay weak.
Quality is good. Many people will pay for quality when they can find it; people are downright amazed when they can get quality for free. But the majority of available products are going to remain Wal-Mart quality, because the vast majority of people are still going to get whatever is on the shelf at Wal-Mart.
And their world won't end. But its shine may tarnish a lot more easily.

Just about everyone I install Firefox for (almost all non-geeks)... People who don't give a shit just plain don't know about it. Firefox is faster, it has a nicer interface, and prevents things like popups and bad security practice within the browser environment. The people that start using Firefox by force (by me) usually thank me profusely and rave to me (and their other non-geek friends) about it within 30 minutes of using it.
Plus, just look at the themes!! Who doesn't like themes??

This bug however allows to break cross-domain scripting boundaries.
A practical example is that an attacker could craft a web page so that when a slashdotter visits it, it automatically submits a silly comment in reply to a particular post (yes, in spite of the hidden formkey field.)
Worse things could be done, like automatically grabbing the last 10 emails from your hotmail account if you happened to be logged in, send random replies to them, etc...
Use your imagination.
Describing this as a way to "completely spoof the address bar" misses the impact of this bug entirely.
All in all, a pretty cool exploit. I can't help but wonder if the double use of ExecScript and setTimeout is really necessary, but maybe that's an attempt to make it work accross more environments.

The first involves an Improperly Closed Tag [jehiah.com] and will crash the browser.
The second is an Inline List [jehiah.com] which will peg the cpu.

St. Peter answered, "Those are Software Vulnerability Clocks. Every computer program on Earth has a Software Vulnerability Clock. Every time a program is compromised due to a bug in the code, the hands on that program's clock will move.
"Oh," said Bill, "which clock is that?"
"That's the UNICOS clock. The hands have never moved, indicating that it was never compromised by an attacker."
"Incredible," said Bill. "And which clock is that one?"
St. Peter responded, "That's the OpenBSD clock. The hands have moved twice, telling us that the "Only one remote hole in the default install, in more than 8 years!" was compromised only two times in this operating system's life."
"Where's Internet Explorer's clock?" asked Bill.

Javascript is the work of the devil. IT IS TURNED OFF in my browser. Obviously ActiveX is even worse and it is turned off as well. Now that is what I call secure browsing. Much better than the security through obscurity that a javascript enabled Firefox browser gives you.
Of course you can turn off javascript in Firefox too, but I bet not many of you leave it that way. In IE I can leave it off because I just enable it for a select few "trusted" sites (mostly e-commerce sites like Newegg or Amazon that I have purchased from before).
In God's name WHEN is Firefox going to implement javascript whitelisting or security zones as a standard feature? Whitelisting is available for cookies, so why not for javascript as well?
