Firefox frustrations

Any of various automation which wrests control away from the user with a default/setting which needs reversing.

• privacy.resistFingerprinting = true

This will cause UTC time to be used for website display and (screenshot) file modification time.

Odd things related to the install.

• If sound fails for firefox but works for other things, check if sndio is installed and remove that.
• Firefox from pkg also requires pango compiled with libthai option, pango pkg does not have this.
