bogus_performance_data_webide.png
STR:
1. Navigate Android Firefox to https://dl.dropboxusercontent.com/u/40949268/emcc/10kCubes/10kCubes.html
2. Open WebIDE on desktop and attach to phone (tested via USB).
3. Start running a performance profile in Performance tab of the developer tools.
Observed: The display shows bogus data ("avg -25.01 fps"). The numbers get larger and larger to negative to something like -800fps, and then they wrap around to +1000fps.

Sorry, this got lost on my triage search, I've adjusted my search parameters and I'm catching up.
Does the FPS ever work on Android? jsantell said that the FPS is occasionally flaky. I'm going to tentatively do a P2 if this happens specifically with this STR, but not more broadly across every use of the perf tool on Android. If it's a broader issue and happens any time you connect to Android I'll set it to P1. I'll need to get my hands on an Android phone to debug this one.

Now that we replaced the old performance panel by the Firefox Profiler (see Bug 1668219) we're closing bugs related to this. Note that the new profiler doesn't have FPS information.
