Here's the sequence of events:

1) Start FF on my MBP (OS 10.8.2), and retina display works properly.

2) Connect my MBP to a 24" external display, which has max resolution of 1920x1200 (set as primary). FF displays nicely on external display.

3) Disconnect external display and FF is now pixelated on MBP retina. Refreshing System Dispay preferences doesn't seem to help, or I haven't found the magic technique.

4) Restart FF and all is well.

So the issue appears to be FF not recognizing the need to revert to Retina resolution.

Try to set the Integer pref gfx.hidpi.enabled to 2 on the about:config page.

Hmmm. Now seeing strange behavior with search bar autocomplete list being cut off (attached example).

Try to disable hardware acceleration in Firefox.
