User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:32.0) Gecko/20100101 Firefox/32.0 Build ID: 20140825202822 Steps to reproduce: Probably a hardware combination of Windows 8.1 and an Ivy Bridge Intel CPU is required - people have been complaining of stutter with this particular setup on Adobe forums before, for example. The Firefox setup consists of Firefox 32 (stable release channel) with no add-ons and no plugins currently enabled. Animation test: http://www.stagexl.org/temp/spine/example.html Video test: https://www.youtube.com/watch?v=4V0N1x675FQ Audio test: http://webaudiodemos.appspot.com/MIDIDrums/index.html I've tested for the same behavior under the same system running Ubuntu 14.04 64-bit (whatever version of firefox Canonical ships Ubuntu with) and a desktop running Windows 7 and an AMD FX CPU with Firefox 32 - on both targets similar behavior couldn't be observed. Chrome does not experience the same issues and runs the tests smoothly. Actual results: Animation experiencing lag spikes and not being smooth, as visible to a naked eye, especially so when other tabs are open. Visible stuttering of video on YouTube at varied frequency of lag spikes. Severe, persistent stuttering and crackling of audio for the MIDI Drums WebAudio demo. Expected results: Animation should have been smooth regardless of other non-media content being browsed. YouTube video should have been played smoothly. Audio should have been clear and with no crackling.
Putting the laptop on 'maximum performance' mode seems to get rid of most of the stutter, also getting rid of crackling in the WebAudio demo. Chrome, on the other hand, doesn't seem to mind such changes and experiences no differences.
WebAudio demo still experiences severe stutter when it's not the active tab, i.e. when other tabs are viewed. I'm done conversing with myself for now!

Hi reporter, User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:43.0) Gecko/20100101 Firefox/43.0 Build ID: 20151223140742 User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:46.0) Gecko/20100101 Firefox/46.0 Build ID: 20160106030225 I have tested your issue on the latest release(43.0.2) and the latest Nightly(46.0a1) and the animation and video played smoothly and the audio was clear and had no crackling sounds. I don't have a laptop to test this so my tests were done on a PC. Also I personally own a PC with Ivy bridge i7 processor at home on which I ran win 8.1 together with Firefox browser for more than a year and could not observe this behavior. Could you please try to reproduce your issue on the latest release(43.0.3) and the latest Nightly (https://nightly.mozilla.org/) and provide the results? Thanks, Cipri

I ran the tests again on Firefox stable (43) and Firefox aurora (45). 1. Some stutter on StageXL when compared to Chrome and FF45 aurora with e10s enabled - I ran performance profiling, and there's more frame drops in FF43 stable, resulting in average of ~38.5 vs. 58.5 FPS. FF45 has a lot more consistent performance with extremely minor drops in the graph. 2. No problems with the YouTube video. 3. No problems with the sound test. I believe this can be closed; I had honestly forgotten about having filed this bug after switching to running Linux as my primary OS. Considering how... a) Windows 8.1 and Ivy Bridge are becoming less relevant with newer architectures _and_ Windows 10 upgrades happening b) Two out of three problems not observable at all and c) Future Firefox versions with e10s eliminate the final complaint of pauses/frame drops d) The report being of a Firefox version 11 versions behind current stable ...I consider this no longer relevant for any investigation, regardless of what might have been the actual cause of performance issues that led to me filing this (i.e. Firefox itself or some past configuration degrading the performance). Thanks for bringing my attention to this!
