1235911 - Firefox freezes when pressing modifier key in save dialog

Status: RESOLVED WORKSFORME

(Firefox :: Keyboard Navigation, defect)

Description

[nicholas.chandoke]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:43.0) Gecko/20100101 Firefox/43.0
Build ID: 20151221065651

Steps to reproduce:

Press Ctrl-S to open save dialog. Then press either ctrl, shift, and maybe alt (haven't tested.) FF freezes only if a modifier key is pressed when the filename text field in the save dialog has focus.
Using Linux 4.2.5-1-ARCH x86_64, FFv43.0.1


Actual results:

Firefox freezes.


Expected results:

Should have not frozen, allowing keyboard-based text modifications via the appropriate combinations of modifier keys.

Found that this bug is really a GTK problem; the problem can be reproduced in any GTK application using a file dialog. (specifically, using --gtk-debug=text in terminal, we can see that the hang is an infinite loop of

Gtk-Message: Looking up keycode = 50, modifiers = 0x0000,
keyval = 65505, group = 0, level = 0, consumed_modifiers = 0x6002

Will add to GNOME's bugzilla.

Following the reporter's steps I am able to confirm that the issues doesn't happen anymore on Ubuntu 20.04 on any of the current versions of Firefox Nightly 87.0a1 (2021-02-16), beta 86.0 and release 85.0.2. No crashes occur under the given test case.
