https://addons.mozilla.org/en-US/firefox/addon/download-youtube-videos/ The above addon leaks zombie compartments in version 12.8 (and possibly earlier versions) steps to reproduce: 1) navigate to a video page youtube.com 2) press save video button in toolbar to start download 3) cancel download (optional?) 4) check about:memory and see compartment for youtube still there.
Andrew, did you contact the author?
The developer was contacted during the review and I included the bug url in it.
current version (12.9.4) still has the issue. Steps to reproduce revised to: 1) navigate to a video page youtube.com 2) close tab 3) check about:memory and see compartment for youtube still there.
version 12.9.6 seems to fix the issue so closing.
(In reply to Andrew Williamson [:eviljeff] from comment #4) > version 12.9.6 seems to fix the issue so closing. I am using Version 12.9.6 and still have the same issue. I didn't response until now because I thought it was another YouTube Download add-on that was causing the problem and then I found this bug report. So could you please reopen this report and notify the developer? Thank you.
The add-on is no longer on AMO. Where did you get it? In any case, these add-ons bordered on malware even on AMO. Off AMO, zombie compartments are probably the least of their problems.

I went to the url that was posted above, and it said "This add-on has been disabled by an administrator.". Then how come Mozilla didn't disable that add-on in my add-on list (like you did with Java)? Anyway, I have disabled it and everything is back to normal, no more zombies left on my desktop whenever I start and/or restart FF. I'll completely remove it now. Thank you again.
We don't blocklist add-ons for these kinds of issues unless they're seriously affecting large numbers of users.
