User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:42.0) Gecko/20100101 Firefox/42.0 Build ID: 20150816004012 Steps to reproduce: Open a file dialog (for example save or open file, save image or link). Type the first letters of a directory or file name followed by pressing Return. Actual results: Nothing. No highlighting of any directory or file, no quick keyboard based navigation within the file dialog. Expected results: When I am using a file dialog, usually you can quickly jump through directories by typing the name of it and it will be highlighted. To go to a "Documents/Downloads/firefox" directory, you would type "Docu" [ENTER] "Down" [ENTER] "fire" [ENTER], and you would be there. Quite quick and it is handled like that in pretty much any other file dialog I can think of.
This time the Component field should be correct. Sorry for the mess.
I see Firefox matching gedit's save file behavior for GTK3 save dialog. The open dialog allows navigating as you mention. I believe this is expected GTK behavior.
The open dialog does not work for me either, but it actually seems to be an issue with the GTK3 file dialog, not Firefox explicitly. Is there a way to turn that functionality on or off when calling it?
I never collided much with the GTK file dialog, but it seems to be *uhm* ****. PLEASE choose something else!
AFIK we are using the expected file picker. Checking with the project devs to make sure. Andrew or Glandium see comment 0.
