The PicPasso add-on creates zombie compartments after clicking its toolbar button. The following steps create a zombie compartment, but they may not be the only way to do so, and not all of the steps may be required: 1) Visit http://gmail.com/ 2) Press the PicPasso toolbar button (at this point, security is broken for the page) 3) Close the tab After minimizing memory multiple times, the following related compartments remain: http://googleads.g.doubleclick.net/pagead/viewthroughconversion/1015888343/?random=1331667169853&cv=7&fst=1331667169853&num=1&fmt=2&value=0&label=aV-CCKGCwgIQ1_O05AM&bg=ffffff&hl=en&guid=ON&u_h=800&u_w=1280&u_ah=800&u_aw=1280&u_cd=24&u_his=1&u_tz=-240&u_java=true&u_nplug=12&u_nmime=199&url=http%3A//www.picpasso.com/register&ctc_id=CAIVAgAAAB0CAAAA&ct_cookie_present=false [pid=Main] https://accounts.google.com/ServiceLogin?service=mail&passive=true&rm=false&continue=http://mail.google.com/mail/&scc=1&ltmpl=default&ltmplcache=2 [pid=Main] Author CCed.

Jan: is there any update you can give us on fixing these memory leaks?

The developer could not reconstruct the memory leaks in Firefox 11, but is currently trying to solve it. I will let you know, if I hear more from him.

Jan: did the developer manage to solve the problem?

We cannot reconstruct the zombie compartment. Therefore we canot really solve it... Would it be OK to upload a new update, which can be tested again?

If you can't reproduce with your current version with the steps in Comment #0 then yes. We will check it again.

Jan, are you working on an update for us to test?

We are currently working on it and i hope we can submit it next week. Sorry for the delay...

Jan: I see your latest version was reviewed and the editor still found the leak - do you not see the leak with the steps to reproduce in Comment #0?

Hello all, I'm Igor, the principal developer. Jan is away, so I'll take over. As Jan said, I followed the steps from Comment #0 but could not reproduce the memory leak. 1. When I start Firefox, I see only one PicPasso-related compartment: picPasso.sqlite. 2. After opening gmail.com, a number of PicPasso-related compartments appear, mainly inner windows with the uri about:blank (for PicPasso's own windows), but also some external. 3. However, when I close the Gmail tab, reopen about:memory and click 10 times on "Minimize memory usage", I see no PicPasso compartements, except the picPasso.sqlite. There are some inner windows, but, to my understanding, they belong to firebug. Is there a possibility to post screenshots?

Igor, which version of Firefox are you using? If it's FF15, the fix in bug 695480 might be preventing the zombie compartment from manifesting.

I can no longer reproduce this issue.
