Yes, Busy posted some good links.

Afaik, the Moz folks follow a "silent support" policy. They firstly aim to support the W3C specification, and then they quietly add support for proprietary stuff. One example is Gecko's support for the innerHTML method, which is an IE thing.

W3C's Amaya web browser probably most accurately implements the spec. Its only disadvantages are it's not really leading the pack in terms of features and development. It's just a good example of how to properly follow the spec.

No browser fully supports any version of HTML, even the browsers that do support some things they don't support everything of it, mailto for example, if you use the subject/body option of the tag it wont always work in later versions of IE, empty td tags give different effects in different browsers, background (html not css) tiles differently in tables ...
marquee etc will work in firefox but not netscape, blink is a netscape tag

http://www.mozilla.org/docs/web-developer/ states: W3C's HTML 4 Specification (mostly supported by Mozilla) more info here http://www.mozilla.org/docs/web-developer/quirks/quirklist.html
Opera also has a page on what they do and dont support (http://www.opera.com/docs/specs/), IE dont have a page as far as I know

You can only list browser specifics per versions, i.e. IE5 vs NS4 or NS6, IE5.5 VS Mozilla1, IE6 vs Opera6 ... to get real answers otherwise it's meaningless as what didn't work two versions ago does now, or what worked last version doesn't work now.

OK, thanks Abhishek

About Firefox: Is it compatible with all HTML tags? I've just downloaded it and tested it with , , , and mailto. They all work fine. Is there anything Firefox DOESN'T support?

was the Netscape version of

I don't think tag support is as important now as it was a few years ago. The pressing issue now is CSS support and maybe DOM compatibility. With simple tags like one can build a page with HTML that's perfectly supported across all platforms, yet style it with CSS that is inconsistently supported. Similar issue with the DOM and Javascript methods.

Four years ago, you could find pages online showing tag support tables for the big browsers. Now you'll more likely encounter CSS support charts.
