Comment 11 for bug 875538

I concur. What I would also expect to see is Firefox maxing out both cores for approx 2-5 seconds as it unloads firefox-bin and plugin-container - this CPU peak does NOT happen if the user has been viewing Flash 11 content off Youtube... from their standard player. If I use iPlayer or 4OD - it seems to close down cleanly. There are also other times when the cleardown happens neatly.

It's made more complex in that Youtube seem to use a number of playout clients.

Re the unload cycle - it's almost like the UI is the only thing that unloads when the problem is experienced. You may have received the issue earlier - IF the problem didn't stand in the way of ubuntu-bug being able to submit the content. However, if Firefox cannot reopen and open the new tab - that incident is never logged. To submit mine, I had to kill Firefox-bin, then go and look at ubuntu-bug's doccos on how to log the data to the local filesystem, then once back in Firefox, get it to replay the incodent and push the data.
