IE5 Released - Not HTML4, CSS1 or XML Compliant

Thursday March 18th, 1999

IE5 is out, and not only is it incompatible with CSS1, but it's DOM is faulty (and proprietary) and HTML4 support is incomplete. Also, it's XML Namespaces implementation is just plain wrong. It does poorly on the Import test, and renders the boxacidtest improperly (and badly).

On an interesting note, the article I linked to above was available this morning. Now, if you go to and find the same article (it has a new link), you'll find that all of the criticism regarding MS's standards compliance has been placed on a second page of the article. Look at the two links to see what I mean. Curious, no?

In response to criticism of their standards support, Microsoft's Mike Nichols said, "It's ironic that people are challenging our standards support when we have led by a substantial margin in this area since IE4". As I mentioned before, expect Microsoft to blame Netscape for Microsoft's lack of 100% standards compliance. The first person to point us to a new article that makes this claim (Microsoft already stated something similar months ago) will get a MozillaZine T-Shirt, when they come available. Our T-Shirts are still in the design phase, but we expect to have something soon.

Folks, stay calm. The Mozilla team is working hard to get a basic browser/mail-news reader into your hands that you can start using full-time. If you need standards compatibility, just go to our fetchBuilds section and download the latest build for your platform. You can see how the new browser, "apprunner", is shaping up, and try out your pages in the testbed viewer, undeniably the most standards compliant browser on the planet.

As for whether 80% is better than 10% compliance or not; it's irrelevant. The key factor in moving the Web forward is the amount of standards which the two major browsers have in common. The least compliant browser was Netscape 4.x on Tuesday and it's still Netscape 4.x today - no change. Web designers have to cater for both major browsers.

When Netscape 5.0 comes out, IE5 will be the browser holding us back. Until then, it's still Netscape.

By the way, I haven't downloaded IE5. I tried Windows Update, it didn't work. Finally I found the "win95" download procedure, which you download a small program that then downloads the rest for you.. the small program downloaded, but it doesn't manage to download anything else. Having said that, Netscape's Smart Update didn't work either (I wanted 4.51).

(I'm installing the new mozilla build, and it downloads perfectly. Ho hum. You can get the developer stuff with no hassle at all, but the finished, consumer-ready versions are impossible to obtain...?)
