Firefox GTK3 file picker is flaky when using oxygen-gtk GTK3 theme

[Mr_Bumpy]

I just thought I'd let you guys know that the file picker in the new GTK3 Firefox build does not work correctly when using the oxygen-gtk GTK3 theme. None of the "places" links on the left do anything, and sometimes clicking on a filename starts a drag operation rather than selecting the file. The only way I have found around this is to go into System Settings -> Application Appearance -> GTK and set the GTK3 theme to "Adwaita".

You'll also want to set the font and font size to match your system's "general" font (default: Ubuntu 9).
