Pressing Enter on "Browse" button in <input type="file" .... /> causes FF first
to show file request and second, to submit form data in one action. Additionaly
it's possible to open file selector while waiting for response from http server

subpage.

Reproducible: Always

1. Using tab set focus on "Browse" button in <input type="file" ... />
2. Press enter


Actual Results:  
File selector opens, but form is submited too.

Expected Results:  
Do not submit form.

Not sure if this means it regressed on the branch, or was fixed on the trunk by
something I can't find, but confirmed in Mozilla/5.0 (Windows; U; Windows NT
5.1; en-US; rv:1.7.3) Gecko/20041021 Firefox/1.0, while Mozilla/5.0 (Windows; U;
Windows NT 5.1; en-US; rv:1.8a5) Gecko/20041018 Firefox/0.9.1+ does the right
thing and doesn't submit on pressing enter on a Browse button.

Mozilla 1.3 - 1.6 also behave correctly.  (I got lazy and didn't check 1.0 -
1.2, but I imagine they're OK.)

Comment 4

[jsp]

With 1.8a6, pressing Enter while the focus is in the file input's text box
triggers the bug.  (This is also true with 1.7 and FF 1.0.)  The bug is
therefore only partially fixed in 1.8a6, unless this behavior qualifies as a
separate bug.

For what it's worth, the form's submit handler gets called, but does not run to
completion before the form is submitted.  (Or maybe any requests to prevent the
event's default action are ignored.)  In any case, it cannot prevent the submission.

Comment 5

I should have reread that last comment more closely before submitting.  By
"triggers this bug," I mean that pressing Enter when the focus is in the file
input control's text box causes the form to be submitted.  No file picker comes
up.  (That, at least, is a good thing.)

Sorry for the bugspam.

Submitting from enter in the input's text field was intentional, in bug 111689,
and then submitting from enter on the Browse button came back out in bug 252526.
