1071662 - Setting dom.popup_allowed_events to "" blocks file input windows

Status: RESOLVED DUPLICATE of bug 918780

(Core :: DOM: Events, defect)

Description

[Mike Conley (:mconley) (:⚙️)]

STR (according to bug 1071302):

1) Open about:config and set dom.popup_allowed_events to ""
2) View some Bugzilla bug, and choose to add an attachment
3 [review]) Click on "Browse" to open the file input dialog

ER:

Native file input dialog should open.

AR:

No dialog, and no user feedback about why.


Now, I know that the likely reaction to "Doctor, it hurts when I do X" is "Well, don't do X!" - so the user should probably not have set dom.popup_allowed_events to ""... but it strikes me as odd that we'd somehow equate the file input dialog with a traditional dialog. That seems like a mistake, and an unnecessary footgun.

Happens here on Linux Firefox 32.0.2 (mozilla.org version) with the gtk-filechooser, too. Not only for empty string, but for removing the "click" and "mousedown" events, too.

I think widgets, which are part of other widgets should not suffer from this restriction and popups, which belong to xul or even native dialogs should not be restricted, too.
