Could you please provide more information? This site seems to work fine for me in e10s.

Not reproducible with e10s disabled.

Could you please try in a fresh profile with no add-ons installed? Also, what platform are you using?

Platform : Windows 10 x64
4GB RAM

So this bug doesn't always happen. The best way to reproduce it is to have Google+ (fully loaded, and logged in) opened in the same window.

In 38.0a1, build 20150204030234 with a fresh profile, Mac 10.10; I can't get this player to work in an e10s window at all with drag and drop. Using the file uploader (by clicking on it) will upload files but the tab seems to hang. The tab stopped working, then the browser hung though there is no crash reported, and I don't have any tabs loaded other than the start and first run pages. I'll try a bit more later to reproduce the crash as you describe and give some exact STR.

In a non-e10s window I can drag files onto the player and play them, and clicking the file uploader also seems to work ok.

I haven't mentioned a crash at all. This is exactly what happened.

Here is the process that was hanging - not sure if that helps.

I can't seem to reproduce this bug anymore, but maybe someone else should confirm this as well.

The music player doesn't cause the browser to freeze for me.  marking WFM

Works fine for me now in Nightly with e10s enabled. I tried a few times with a fresh profile, multiple tabs open, and uploading a few files.
