when trying to add attachment to a bug, filepicker doesn't start when the "Browse" button is clicked. No error messages. Saw this first in build 2000090621. Uncertain about component. Filepicker as such can be started from file-menu "File/open file..."
This was a bug filed about a tar.gz build. According to invalid status in bug 51330, only Installer builds are valid to file bugs about. I wasn't aware of this. Setting invalid.
