***** See Web Extension notes below ****
The extension can validate the HTML sent by the server or the HTML in the memory (after Ajax execution).
The details of the errors are seen when looking the HTML source of the page.
The extension is based on Tidy and OpenSP (SGML Parser). Both algorithms were originally developed by the Web Consortium W3C. And now extended and improved by a lot of persons. Both algorithms are embedded inside Mozilla/Firefox and makes the validation locally on your machine, without sending HTML to a third party server.
Each algorithm has advantages and inconvenients. The program will give you the choice at startup. But mostly,
- The SGML parser is the same program than the one running behind validator.w3.org.
- Tidy has accessibility check for the 3 levels defined in WAI
- W3 Online validator to validate HTML 5 pages
The extension is translated in 17 languages.

HTML Validator 0.98 is the first Web Extension version.
Firefox old XUL extension do not work anymore with Firefox 57.
It is a complete rewrite of the code.
The extension works now differently:
* There is a new tab in Developer tools: Html Validator.
* The validation happens only when the 'Developer Tools' is open.
* The extension uses a new version of Tidy 5 compiled from C to Javascript. It works now on all platforms.
* It works in Chrome
Some features from the 0.97 are still missing. See here for more details.

xmptool 2.2
Download Html Validator For Chrome
2019-01-11 Version 2.2 of xmptool adds support for qualifiedproperties (structured values that include the specialrdf:value property). Previously only certain trivialcases were supported. Also, xmptool no longer outputs qualifiedproperties if the property has zero qualifiers: It outputs a simpleproperty instead. E.g., it can read <x:proprdf:value='xyz'/>, but outputs it as<prop>xyz</x:prop>
