Steps to reproduce:

Downstream (Ubuntu) bug report: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1893021

With the release of firefox 80.0, loading the flash plugin on Ubuntu 16.04 was failing with the following error:

    /usr/lib/firefox/plugin-container: symbol lookup error: /usr/lib/firefox/libxul.so: undefined symbol: gtk_window_set_titlebar

Actual results:

In previous releases, loading the flash plugin worked fine.

Expected results:

This regression was caused by two recent revisions: https://phabricator.services.mozilla.com/D84623 and https://phabricator.services.mozilla.com/D82804, which added GTK function stubs (in widget/gtk/mozgtk/mozgtk.c in the wrong section (they were added to the COMMON_SYMBOLS section but they should be in the GTK3_SYMBOLS because they are GTK3 only).
