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.

#14 IE 5 is really IE 4.5

Okay, nothing to do with the Macintosh version, but IE 5 really is IE 4.5!!!

Look through the registry and you'll see heaps of references to it being IE 4.0, and just having registry entries to pick up the 5.0 versioning.

Basically I think Microsoft has smacked a few bits and pieces into IE 4, changed the back end a bit, and optimized it... Yes! Optimized!

Bravo to Microsoft for this coding feat: Well done! ;)

I wouldn't be surprised if they shelved half their compliance plans for IE 5 and concentrated on user-seen features after the kerfuffle that Mozilla/Netscape/AOL have been making.

Looks like they're running scared!

Perhaps they'll release a service pack for IE5, or a 5.5 version closer to the Mozilla date so they can have me-too compliance... But then... How many users are update fanatics like us?!?

Keep the good code rolling!
