Actual Results:
Nothing happens when the field is clicked.

Expected Results:
Focus should be moved to the input field,

This is likely a regression from bug 607417.  This bug does not appear in Firefox 4, but it does appear on Aurora (Firefox 5) and Nightly (Firefox 6).

test case

This affects more than just form fields.  Clicks are not dispatched correctly to position:fixed elements in Fennec.  Steps to reproduce:

1. Open the attached test case in Fennec.
2. Zoom in, then scroll down.
3. Click on "Click me."

Expected results: The link is activated, and navigates to
Actual results: Nothing happens.

Another good reason to turn off position: fixed layers for now.

Filed bug 656167.

It looks like events are not properly redirected to content with fixed position...
it is possible to enter/activate input fields if your page is scrolled to (0, y) position, and if X!=0, then events are redirected somewhere else..., also page automatically centered if you click on input field (X!=0) and in order to switch to password field you need to scroll page back to X=0 position and then click on password field..
do we have any magic in events coordinates translation code when they are sent from Parent to Child? scroll offsets? 

also interesting that different Y- position does not break this behavior.

We'd like to get this behavior into platform. See bug 652240.

fixed by bug 656167, but we hope to turn position:fixed back on, so leaving this open.

I also tried to reproduce this following the steps from Comment 2 and it's not happening. Should we mark this as WORKSFORME?

This works for me as well using a current Nightly. Cork reopen if you can repro.

Fix click for fixed layers after zoom

Ok, so link clicking broken after zoom, but works again after little scroll, which make it clear that problem is in missing updateCSSViewport after zoom animation finished...
