Jump to: navigation, search

HTML5 Forms is a part of the HTML5 specifications about forms. It introduces new elements, and new input types which aim to help web developers to not re-invent what is already well known. For example, with HTML5 Forms, web developers will not have to write javascript code to tell you a field is required or to check your email address is valid.

Shipping Criteria

In order to ship in a Firefox release, each HTML5 form element must be complete to the following criteria:

1. It must include pleasant and working UI, where appropriate.

2. You must be able to use CSS to style the element, especially the UI that we generate. This includes any pre-defined pseudo-selectors (invalid, required, icon, etc.)

3. If there's a constraint API the API must be complete.

4. It should be fully accessible.


1. Validation done - touches all text-based fields.

1a. Requires UI

1a. Support for CSS pseudo-selectors

2. Telephone

3. Email

4. URL

5. Search

6. Range

Implementation status

Wikipedia offers a non-exhaustive overview of the implementation for the main layout engines: http://en.wikipedia.org/wiki/Comparison_of_layout_engines_%28HTML5%29#Form_elements_and_attributes

A comparison between the different browsers: http://www.findmebyip.com/litmus/#html5-forms-inputs

The patch queue

As much as possible, the patches related to HTML5 Forms are landed to mozilla-central so you may have some HTML5 Forms features in Firefox nightly builds (aka Minefield). However, for various reasons, some patches have to wait before being landed to our tree. These features are marked "Ready to be landed" in the summary below.

A patch queue has been created with all patches ready enough to be tested. That includes the "Ready to be landed" patches but also some WIP patches. You can found this patch queue here: http://hg.mozilla.org/users/mlamouri_mozilla.com/html5forms-patchqueue/

Using the patch queue

To use the patch queue, you have to clone mozilla-central then clone the patch queue, apply the patch and build. These can be summarized with these instructions:

# You need to be in a directory where you want to clone mozilla-central
hg clone http://hg.mozilla.org/mozilla-central/ src
cd src/.hg/

# Get the patch queue
hg clone http://hg.mozilla.org/users/mlamouri_mozilla.com/html5forms-patchqueue/ patches
cd ..

# Apply the patch queue
hg qpush -a

# Build Firefox (you need a mozconfig file)
make -f client.mk

To update the patch queue:

# Update mozilla-central (you need to un-apply all patches before)
cd src
hg qpop -a
hg pull -u

# Update the patch queue
cd .hg/patches
hg pull -u
cd ../..

# Re-apply the patch queue and re-build Firefox
hg qpush -a
make -f client.mk 

If you have any trouble while applying the patch queue or building Firefox with this patch queue, let me know by email (you should found it easily in any bug listed below). If a feature isn't working correctly, please leave a comment in the related bug.

Feel free to send me an email if you think a patch could/should be in this patch queue.
