techentin writes " CNN Money is reporting a new and improved MyDoom variant which is spread by a hyperlink in email. Clicking the link connects the user to an infected machine, which exploits a recently discovered buffer overflow in Internet Explorer. McAfee has a more detailed description. Is this yet another good reason for running Firefox?" CNET also has a story.

CNN Story (Score:5, Insightful)
One of the coworkers downloaded FireFox right away. I actually expected him to take a little while to wean off of IE. After I showed him FireFox's features, however, he set FireFox to his default browser and deleted his IE shortcuts! I think we're definitely making headway.
Re:CNN Story (Score:5, Insightful)
Okay, I'll grant you that FireFox is probably more secure than IE. But to say it lacks security issues is going a little further than I'd go, myself. In fact, I'd be willing to bet you $10 that it has security issues of it's own.
Don't sell your friend a dream. Set his expectations realistically. No software is bulletproof. No software lacks security issues.
Firefox f-ing rocks, no doubt about it. It blows IE out of the water. It probably has far fewer security holes. But to say it "lacks security issues" is naieve.
Don't believe everything you read on slashdot. A lot of these people have an agenda to meet.

Remember how FireFox handled the download bug? Old copies of the browser would actually be redirected to an auto-update site. Click a button, wait for a few kb download, and voíla! A secure browser.

Hmmm.... I can think of one:
how about:
#include
int main(){
printf("Hello World!\n");
}
I dare you to find a security hole or other issue in that one! Probably better to say "it is unlikely that any nontrivial software will be without security holes or considerations."
I run Qmail, and it certainly has its security considerations (no holes though). Security issues with Qmai
Re:Software without security issues: (Score:5, Informative)
While your assumptions are most likely correct, complacency is the friend of the buffer overflow. Depending on your implementation of the clib, printf, usually considered safe, could possibly be a problem - particularly as it ends up using the locale system and the user settable LC_NUMERIC to determine how to represent numbers, radix, etc.
My favourite printf gotcha however is the seldom used %n conversion character - unlike it's brethren, this one writes data to the pointer in the argument list ( the number of characters printed so far ). This can be used to scribble over various pointers in the arg list and is why you should never, ever allow users to provide format strings to the program without vetting them first.

The last security bug I remember hearing about in Firefox had a working patch to fix the problem very quickly. In fact, it was released by about the time I had finished reading the alert in the first place. Microsoft, on the other hand, takes considerably longer.
It's one thing to admit there are security vulnerabilities in Firefox. There have been, and there will continue to be vulnerabilities discovered in Firefox. But as long as the Firefox community fixes these vulnerabilities as quickly as they have in the past, I don't think it's fair to say that Firefox has security issues.
Microsoft, of course, has both security vulnerabilities and security issues. It becomes an issue when the vulnerabilities aren't dealt with quickly enough.
Semantics, I know.... But there is a crucial difference.

1) Go to www.BigNewsSiteorFaveBlog.com
2) Decide you want to read 15 of the 30-40 news articles available to you.
Then either:
3-Tabbed) Click on the things that look interesting, and keep clicing on interesting while the 15 news articles load in separate tabs. By the time you've clicked the 15th thing, 10 of the 15 articles have already loaded and been rendered for you in their tabs. Hover the mouse button over an "X", and click once to close the tab without moving. (sweet on a conventional mouse, and really sweet on a touchpad-based laptop!)
or:
3-Untabbed-option-1) Click on the interesting thing. Click "back" (hoping that the stupid marketroids at the website haven't borked "back" on you). Click on the second interesting thing. Wait for the HTTP session to start. Read the article. Click "back" (and wait for the HTTP session to start as the original reloads). Click on the third interesting thing. Wait for... [repeat 15 times].
or: 3-Untabbed-2) Click on the interesting thing in a new window. When window focus changes to the newly-popped-up window, curse, and click on the first browser window. Click on the second interesting thing to pop up the next article in a new window. When window focus changes, curse, and click on the first browser window. [ ... repeat 15 times.]
If you read at the pace of a slug, and/or spend more time scrolling the article because you render all fonts in 24-point Gothic, tabbed browsing offers little advantage, because you spend a lot more time reading and scrolling through the article than you do loading and rendering it.
If you read quickly, and/or cram enough text onto the page to see an entire page with one or two presses of PgDn, the 500-1000 milliseconds of HTTP session initialization, page-loading, and HTML-rendering time is an appreciable fraction of the time you spend reading an article. For CNN articles, we're talking about 5-10 paragraphs of text (5-10K of text, tops) and hundreds of kilobytes of frames, ads, banners, style sheets, and other crap that has to come down the pipe (often requiring multiple HTTP sessions to different websites - DNS lag can also come into play), and that ratio can be significant.
Anything you can do to minimize the amount of time you spend waiting for content relative to reading content is a Good Thing. The larger that ratio of waiting:reading is, the bigger the advantage offered by tabbed browsing.

Most viruses come from people you know, since they exploit the address book feature. Most spam comes from people you never heard of.

Sure, but will those flaws in Firefox as serious as the flaws in IE?
It seems like when Microsoft attempted to integrate IE with the OS, IE was allowed access the OS in some very dangerous ways.
For instance, why would earlier versions of IE write files to any directory without asking the User for permission?

Not as much of a problem though (Score:5, Informative)
The largest problem (mostly the cause of spyware rather than viruses though) is the issue of ActiveX scripting. Because ActiveX controls are trusted on the basis of vendor signature, and because someone can force an old version to be downloaded and installed, it means that no security patch can protect you against a malicious site scripting against a bug in an ActiveX control signed by a trusted vendor. No security patch can be writte to do this without breaking *every* ActiveX control in the internet.
The second issue is that of security zones. This allows an attacker to exploit any flaws that come with the enforcement of such zones. This is an issue for viruses and spyware alike.
Now, it is possible that a new as yet unimagined sort of attack will eventually be possible against some type of functionality in Mozilla. At least one type has (XUL files spoofing interfaces), but if these become a problem, it is open source, and so you or anyone else can pay for somone to make a version with a different structure. If enough people switch, the process begins over again. But each time, I think we are safer.

Windows Update? Active-fucking-X. So unless you move http://*.microsoft.com/ into trusted zone (ramped up to medium security), you cannot get security updates without enabling ActiveX download and scripting.
Even in WinXPSP2, there is still that trusted zone that gives unlimited rights. Like download unsigned activeX controls without prompting. There is nobody I'd give that right to, not even myself. Yet they have it.
Plus all the MSN content pushes AX at you. At least Expedia are not that daft; you can shop there with Firefox. But check out a pure MS site

Another reason Windows isn't ready for the desktop (Score:5, Funny)
I've been running Linux on my main desktop for years, and recently I've really been considering switching to Windows. After all, it's got some cool apps, and while I wouldn't call it "feature complete", I say they've done a good job of implementing many of the best features of Linux and OSX. However it's articles like this that convince me it's still a bit early to switch to Windows.
All told they've made some real inroads in servers, and the desktop experience is improving with each release (the current unstable branch -- AKA "XP" -- has implemented the theme concept long popular in KDE and Gnome!) however I think it's still premature to declare Windows ready for prime time on the desktop.
