Expected results: compartment(http://video.webmfiles.org/elephants-dream.webm) should go away. If Nightly is started in safe mode, this compartment is closed normally. ****************** Main Process Explicit Allocations 64,893,719 B (100.0%) -- explicit ├──41,253,422 B (63.57%) -- js │

That's a tiny compartment. All it has is 920 bytes worth of shapes and then some internal fragmentation.

Confirming. However, this isn't really an Adblock Plus issue - the same leak can be observed with a minimal nsIContentPolicy implementation. This is probably related to bug 708431.
Status: UNCONFIRMED → NEW
Ever confirmed: true
Summary: Zombie compartment with Adblock Plus 2.0.1 on http://video.webmfiles.org/elephants-dream.webm (WebM video) → Zombie compartment with any add-on implementing nsIContentPolicy (Adblock Plus, NoScript, GreaseMonkey) on WebM videos

This extension implements nsIContentPolicy but doesn't do anything beyond that - only logs the calls. The issue can be reproduced with this extension as well.

A patch has been released in FF12 about Bug 708431, it fixes an issue with nsIContentPolicy too. So I tested the latest nightly (Mozilla/5.0 (Windows NT 6.1; WOW64; rv:12.0a1) Gecko/20120109 Firefox/12.0a1) only with add-on ABP and it appears the current bug is fixed too, no more zombie compartment. So I guess comment #3 was true. Anyway both Bug 708431 & Bug 711675 are still present in FF11 (Aurora). In addition, I would like to add the zombie compartment can be observed with various video/audio formats, not only WebM: [*].oga: http://upload.wikimedia.org/wikipedia/en/a/a9/Gordonwilson_bbc_interview_1987.oga [*].ogg: http://www.html5rocks.com/en/tutorials/audio/quick/test.ogg [*].ogv: http://www.html5rocks.com/en/tutorials/video/basics/Chrome_ImF.ogv [*].webm: http://video.webmfiles.org/elephants-dream.webm (restart the browser to test each format one after the other)
