This would be done by adjusting the full-screen-api.transition-duration.enter and full-screen-api.transition-duration.leave preferences in the Configuration Editor for Firefox (about:config page). If you want to disable to effect completely, change the values to 0 0 (zero space zero).

After you restart Firefox, the fading effect should be gone.

Hope this helps.
