Reproducible: Always Steps to Reproduce: 1. install mozmill test suite linked above 2. run test_endurance with greasemonkey as an addon 3. check dashboard Actual Results: Dashboard run http://mozmill.blargon7.com/#/endurance/report/66e0fb6bd5645ddae0ee8e21d000e51b Expected Results: Memory should be released after entering and exiting private browsing mode with the addon installed.
CAUTION: clicking the endurance report in the first comment may crash firefox! A better link is forthcoming
Confirmed based on our results. (In reply to comment #0) > http://mozmill.blargon7.com/#/endurance/report/66e0fb6bd5645ddae0ee8e21d000e51b Please don't click on that link unless you don't want to see your main Firefox instance be frozen. Use another instance/profile for it. Next step would be to get some manual steps or an easy way to reproduce with the Mozmill IDE.

Here is a shorter 100 iteration run that should load ok http://mozmill.blargon7.com/#/endurance/report/66e0fb6bd5645ddae0ee8e21d0011f14
Greasemonkey beta released today showing the same issue: http://mozmill.blargon7.com/#/endurance/report/66e0fb6bd5645ddae0ee8e21d0013bf4
Created attachment 517521 [details] Unusable Leak Gauge log Attempt at getting a leak gauge log with greasemonkey installed causes an unusable log to be generated.
I can reproduce it with Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0b13pre) Gecko/20110310 Firefox/4.0b13pre ID:20110310030427 Steps: 1. Install GreaseMonkey 2. Enter Private Browsing mode 3. Leave Private Browsing mode 4. Repeat steps 2-3. As you can see the memory consumption is raising constantly and memory never gets freed again.
OS: Windows 7 → All
Hardware: x86 → All
It's less noticeable in Firefox 3.6. It's memory consumption also increases but keeps staying at 100MB on my box, while for 4.0 there is no upper limit yet.
Keywords: regression, regressionwindow-wanted
Looks like this has been regressed between Firefox 4 beta 12 and RC 1. I will do checks with nightly builds now to narrow down the range.
Whiteboard: [addons-testday] → [addons-testday][4rc]
Not sure if I'm doing that right, but the results from leak gauge don't show any leak: Results of processing log leak.log : Summary: Leaked 0 out of 0 DOM Windows Leaked 0 out of 865 documents Leaked 0 out of 775 docshells Leaked content nodes in 0 out of 877 documents David, is there another good way to get more information about?
Something else is then perhaps leaking. Some JS objects? Images in the cache? Elements? Btw, has anyone checked whether we leak something on shutdown? I could try to check that later today.
Greasemonkey doesn't seem to observe the private browsing notifications, in case that matters.

> Greasemonkey doesn't seem to observe the private browsing notifications, in > case that matters. That is correct. But what might we do with them if we were?
Nothing I can think of offhand. The point was that this is not a leak due to your code doing something weird in response to the notifications, since your code doesn't observe the notifications. ;)

No longer seeing this issue in latest nightlies with Gresemonkey 0.9.14

I'm curious to know how you retested this. Do you have some reports that show the memory usage does not increase during the private browsing test?
(In reply to Dave Hunt (:davehunt) from comment #16) > I'm curious to know how you retested this.

I only did this test by observing about:memory as I had tried test_endurance but it seems to get stuck on testAddons_OpenAndCloseExtensionList\test1.js with the current nightly and didn't feel up to digging around to disable the test. There appears to be no increase in memory usage or zombie compartments so I thought to close it as there have been a few new versions of greasemonkey anyway. If there's a way to disable that test or just run the private browsing one I can check properly and set to block Bug 700547 if necessary.
