Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:50.0) Gecko/20100101 Firefox/50.0

After a while 30-60 min (depending on amount of visited pages) memory consumption grows up to 1.5-2GB and firefox start lagging. Closing all tabs except one, don't decrease the memory consumption.

I can reproduce this with and without Add-ons.

regression range would be great.

Could you perhaps create GC/CC logs (initially just concise) and send to me? The logs may contain urls and other possibly privacy sensitive data.

Are you using devtools?  There are some known leaks triggered by devtools at the moment.

I'm experiencing this too, since one/two weeks. (will try to narrow the regression-range somewhat tomorrow).

in my current session(~5h) i have:
1,242.66 MB (100.0%) -- explicit
├────686.77 MB (55.27%) -- window-objects
│    ├──566.06 MB (45.55%) -- top(none)
│    │  ├──491.66 MB (39.56%) ++ ghost
│    │  └───74.40 MB (05.99%) ++ detached
│    ├───62.41 MB (05.02%) ++ (9 tiny)


131 (100.0%) -- ghost-windows

most of them are tabs closed hours ago and/or tabs opened in private windows(all closed).

Matthias, do you have any addons enabled?  I also open/close private windows frequently and got leaks due to a simple addon.

Add-ons like 'Element Hiding Helper für Adblock Plus' cause memory leaks.

	Comment 7 • 8 years ago

Yes I am using some addons(Adblock Plus, HTTP Header Mangler, YouTube Plus). My addon-selection has not changed for quite some time(many months).

I am wondering why closed tabs(especially those in private windows) are not discarded when the window is closed?

SpeciesX, initially you indicated "I can reproduce this with and without Add-ons" but in comment 6 you indicate Adblock Plus caused the leak. Can you still reproduce without add-ons?

I'm no longer able to reproduce this without add-ons. I've already disabled 'Element Hiding Helper für Adblock Plus' weeks ago, currently Adblock Plus is the reason for my ghost windows.

Same here, disabling ABP fixes it.

Filed a bug here: https://issues.adblockplus.org/ticket/4203

I guess we can close this bug.

Resolving as INVALID - this was indeed a regression in Adblock Plus, affecting only 2.7.3.4184-beta development build. This issue has been resolved today.

It seems that Adblock Plus 2.8.2 still has the bug: Bug 1326095

Hi guys what do you think we should do here, reopen this one and mark bug 1326095 as duplicate after this?

It doesn't matter too much. Really, this needs a bug in the ABP bug tracker more than it needs a bugzilla bug.

The new bug might be the same issue, or it might be a new issue. I don't know.

	Wladimir Palant
	Comment 17 • 7 years ago

Definitely not the same issue, rather some other kind of memory leak. Either way, I'm looking into it.
