Comment on attachment 825527 [details] [diff] [review] Force flash to use a windowless mode in e10s until windowed mode plugins are fixed This is just hacky wallpapering, but it makes flash work in e10s on linux/windows.

This fix cannot be verified on Fx 28 beta since Electrolysis is not yet supported on this branch: I hit crash bug 947213 after browser.tabs.remote pref is set to true. Removing verifyme keyword.
