HTML Validator Is A Must For Web Developers Rated 5 out of 5 stars

The HTML Validator Add-On is an absolute must for any web developer. It is easy to use, beyond useful, and without a doubt something I will continue to use.

I especially like that with a quick glance I can see how a page validates.

The view source functionality is indispensable.

Indispensable tool for web developers! Definitely the most convenient way to check your page's HTML for W3C compliance.

By the way, there is a Mac OS X build available for Firefox 1.5/2/3 on the developer's site:

This extension is in fact available for Linux, but you have to go to the developers website at http://users.skynet.be/mgueury/mozilla/download.html to download it. For some reason it is listed on this directory as not available but I am in fact using it :)

Great. but crashes gmail Rated 5 out of 5 stars

Great plugin, but I discovered that it crashes Firefox when I search or send e-mail in Gmail. mail.google.com needs to be on the blacklist by default if this behavior isn't fixed soon. Wish I'd known before.

OS X PPC FF3 Rated 5 out of 5 stars

I loved this plugin but it seems they ain't going to release a MacOS X PPC version for FF3, so does anybody know a good replacement?

Quick and easy Rated 4 out of 5 stars

I use the status bar element of the tool to quickly identify pages requiring further consideration.
The fact I can then view the source with the suspect code highlighted is a further benefit.

THE BEST ADD-ON
If you ever create web content, you want this add-on!
This add-on was amazing in the .7* versions but the 0.8* versions are even better.
I have always used this on Linux - Thanks Marc

Rated 3 out of 5 stars

I rated this as a three. Although it does do most things right, it still needs some improving...

Great Add-on Rated 5 out of 5 stars

This is an awesome add-on that has helped encourage me to validate all of my websites that I make from now on.

The only recommendation that I would give is to have it validate the CSS too, as in show the warning symbol if the css is not correct. But the link you have to the w3 css validator helps offset the fact that yours doesn't do it.

Keep up the great work!

A very useful tool. While creating pages it is easy to see where errors were made. I have personally used this tool many times over. Thanks.

Invaluable! Rated 5 out of 5 stars

HTML Validator is an absolut must have for every quality oriented web designer. It has never been easier to create error free pages. The developer is also very responsive.
Together with Firebug and Httpfox it's everything you can ask for.
