[Andrew McCreight (out of office until 8/21) [:mccr8]]

Thanks for filing a new bug!

Bug 1410209 will help diagnose this issue by indicating what the runnable is.

It has only started showing up recently, but that's because I recently landed bug 1411259 to reduce the leak threshold on tab processes. I expect that the underlying leak is older.

Comment 3

[Andrew McCreight (out of office until 8/21) [:mccr8]]

As I said in the dupe, the content process that is leaking this runnable is being created during test_bug1209621.xul. I'll move this to Document Navigation for now.

I rebased my patch for bug 1410209. At this point, I'll probably just wait until Nathan gets back from leave.

Bug 1410209 will have (hopefully) changed this leak to something new.

This has gone away, as expected. The leaks will show up as something else now. Note that this signature (or something like it) will still happen on beta and release.
