As it's not clear, this work on Windows. It's just OS X where it does not work.

There is no information in this bug report indicating which web site is affected by this problem.

Reporter: please ask this on support.mozilla.com, or report here with exact steps to reproduce if you're convinced it's a bug in Firefox.

websites that are accessible by Firefox.

Here is one example
http://cq2.crummett.us/indexnl.php?page=nl_newaccount

1. load http://cq2.crummett.us/indexnl.php?page=nl_newaccount
2. Click on the checkbox
3. Press enter

This works as expected on Windows, but not on OS X.

This is only one page, as an example, but any form with a radio button or checkbox exhibits this behavior.

Cleared cache/cookies, disabled all addons and plugins, and the issue is still present.

For completeness, can you try safe mode and then separately a new profile please:

Presuming it still occurs after that, could you see if you can find the regression range using this tool: (I can only test on Win or I'd try myself)

Tested probably 30 nightly builds. A lot of them failed to run at all.

entire 4.x branch has this defect
3.7a1 does not
3.7a7 has this bug

I ran out of time testing them all. Maybe I can narrow it down later.

Comment 7

[Ed Morley [:emorley]]

If you use the tool in comment 5, it automatically bisects for you, normally only requiring <10 builds to be tested to get the range down to 24 hours of changesets, rather than the 30+ you've tested so far.

> 2. Check/click a radio button or checkbox input element in the form

This no longer focuses the radio or checkbox on Mac, because the OS convention is not to focus such controls when they're clicked.

You can restore the old behavior by setting the preference "accessibility.mouse_focuses_formcontrol" to true in about:config, if you really want to.

See bug 577316 for the discussion.
