The following tests all hardcoded a special value for Timer Precision Reduction. browser/components/extensions/test/xpcshell/test_ext_browsingData_cookies_cache.js browser/components/resistfingerprinting/test/browser/browser_performanceAPI.js browser/components/resistfingerprinting/test/mochitest/test_animation_api.html browser/components/resistfingerprinting/test/mochitest/test_reduce_time_precision.html devtools/client/sourceeditor/test/browser_codemirror.js dom/animation/test/css-animations/test_animation-currenttime.html dom/animation/test/mozilla/test_transition_finish_on_compositor.html dom/media/test/test_video_stats_resistfingerprinting.html dom/tests/mochitest/ajax/jquery/test_jQuery.html netwerk/test/unit/test_race_cache_with_network.js Of these, only test_video_stats_resistfingerprinting.html begins failing when Jitter is enabled. So disable jitter for that test. Additionally, dom/midi/tests/test_midi_packet_timing_sorting.html began failing with Jitter, so we disable it there. (We could easily modify the test so it began passing, but this would reduce the effectiveness of the test.)
