User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:32.0) Gecko/20100101 Firefox/32.0 (Beta/Release) Build ID: 20140818191513 Steps to reproduce: Play music on Soundcloud Actual results: Music plays fine, but CPU is spinning between 60 and 120%. Expected results: Usage stays reasonable.
Did you test in safe mode (https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode) and with a clean profile (https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles)?

Apologies, I should have said that it was a clean profile. I haven't tried safe mode yet.

I'm guessing the sample is from the OS X tools (instruments or the activity monitor). However, it doesn't have symbols so it's very hard to see what's going on. Could you try getting a profile with the gecko profiler add-on instead? See: https://developer.mozilla.org/en-US/docs/Mozilla/Performance/Reporting_a_Performance_Problem .

Ok, I think that I captured a trace: https://dl.dropboxusercontent.com/u/2451223/rBQV1dq1.dms Let me know if you need more info. The Nightly build seems to have the issue a little less. I can run another trace using the Beta if that helps.

Hi, I have tested this On Mac OS X 10.10 with FF Nightly 46.0a1 and I can't reproduce this issue. CPU is spinning between 9% and 38%. Jonathan do you still have this problem? If yes please follow the link given by Gijs: https://developer.mozilla.org/en-US/docs/Mozilla/Performance/Reporting_a_Performance_Problem

I will see if it still repros on my Mac. Thanks for following up!

I see spikes of up to 35% CPU, which still seems elevated for audio playback, but evidently not the end of the world. Perf trace here: https://cleopatra.io/#report=40011b826c5edc5ec03636e666d102093cd450b4

We looked at this during regression triage today and wondered if anyone could post a more recent performance profile? (Assuming there is still a perf issue)

I retested this on Mac OS X 10.10 with FF Nightly 55.0a1(2017-03-13) using the steps from the description. I made a cleopatra profile(https://perfht.ml/2mHiWX7), maybe it is useful. I also attached a print screen with the CPU consumption, please note that this CPU percentages were recorded just for ~2 seconds and after that, the CPU dropped to around ~15-30%. Jonathan do you have any updates about this? Feel free to contact if you think I can help in any other way. Thanks

I haven't used SoundCloud in over a year, and cannot comment on this right now :( I'll try to regress it soon.

I'm still seeing massive CPU use when SoundCloud is open. It can be paused, not even playing music and the tab is still using a lot of energy.
Mac OSX 10.13.6
FF 68.0.2
Happy to record diagnostic info if given sufficient instructions.

Given this bug is attracting junk comments, and we never got to the bottom of a root cause here, going to close this as incomplete. If there are still performance issues on soundcloud, we could potentially reopen, but perhaps a new bug would be more appropriate after all this time.
