I can't reproduce that with FF31 on Win 7.

Could you test:
1) in safe mode:

2) with a clean profile:

firefox-31.0.en-US.linux64

That timer doesn't work (requires Flash?); no flickering with two other timers.

I installed a new OS version, and so I got a new fresh firefox profile as well. Now the flickering is gone. Probably my old profile was the problem which exist since FF17 or so.
