+++ This bug was initially created as a clone of Bug #731875 +++ I see a zombie compartment from www.joshmatthews.net/position.html sitting in about:compartments, and I haven't visited that test page for more than a day. I'll try to find some time to try with a blank profile, as this one has lots of addons present.
All the zombies cause major problems to responsiveness, so [Snappy]
Hmm, yeah, we probably need to clean up the panel when it's hidden, or something.
Created attachment 615793 [details] [diff] [review] WIP Fixes the leak, and hopefully even the tests https://tbpl.mozilla.org/?tree=Try&rev=cb23b9cca906 I can't figure out any way to test this, since this is a runtime leak, and we don't have anything like about:cc running during tests.
This should be simple fix for a rather major snappy-ness problem, so we should try to get this fixed for FF14.
Comment on attachment 615793 [details] [diff] [review] WIP We should probably take this to FF13 [Approval Request Comment] Regression caused by (bug #): NA User impact if declined: Possibly higher cycle collection times Testing completed (on m-c, etc.): passes tests on tryserver Risk to taking this patch (and alternatives if risky): should be low risk String changes made by this patch: NA
Comment on attachment 615793 [details] [diff] [review] WIP (I think you could use a=desktop-only, but you can have a=gavin if you want!)
I think we should wait until we get some small amount of central feedback before landing this on Aurora, FWIW.
Comment on attachment 615793 [details] [diff] [review] WIP [triage comment] snappy, been on central a few days, low risk.
