Not sure what caused that but I ended up with about 300MB only for the Gmail tab. I will attach some output which will hopefully help.

After running the cycle collector with about:cc I still get high numbers:

29457 objects
1194 roots
0 garbage
66642 edges

Olli, anything you would need while I have it in the active session?

    
    

    
  
No, there is no way at the moment to get this reproduced. Sadly I hit 'profile startup' in the profiler add-on which restarted my browser. I will keep an eye on it and report back once I have seen it again.

Gmail tends to take a fair amount of memory.  The only unusual thing I see in about:memory is this:

├──108.43 MB (09.42%) -- window(https://mail.google.com/mail/u/0/?ui=2&shva=1#inbox/13c8ae3b2a70cba6)
│  ├───89.44 MB (07.77%) -- dom
│  │   ├──86.64 MB (07.53%) ── orphan-nodes

The usual question:  do you have any extensions installed?

    
    

    
  
Also: how long has gmail been open?

I usually have gmail open all the time. But have seen this issue only once until now. I'm not sure what exactly has been caused it. If it happens again would even a huge gc log help given that I cannot restart the browser?

    
    

    
  
You should cut out the Ubuntu specific extensions given that I posted the comment from my new Ubuntu machine, but have seen this on OS X.

    
    

    
  
khuey said he's seen this before on his machine.

    
    

    
  
200+ MB seen in Firefox 26.0 here, most of it orphan-nodes.
Similarly orphan-nodes increase when pinging about:memory - seem to be freed only every few reloads.

Mozilla/5.0 (Windows NT 5.1; rv:26.0) Gecko/20100101 Firefox/26.0

    
    

    
  
I haven't seen this for a while. Radoslaw, do you have any steps in how to force this behavior?

    
    

    
  
1. Open web browser.
2. Open GMail, log in.
3. Have GMail in horizontal mode (not sure if critical)
4. Open about:memory, check memory usage. (is around 230 MB here; 140 MB cold)
5. Open another tab, can be empty
6. Wait for about 30 minutes with GMail in background
7. Check about:memory again.

Monitor memory every some time, it will increase over time, mostly due to JS fragmentation, some due to orphaned nodes.
Clicking and viewing mails makes it a bit worse.

Reducing JS GC limits makes it better, but does not fix the problem.

    
    

    
  
Anyone reported this to Google? (Since this sounds like a gmail issue, not FF issue)

    
    

    
  
Doesn't seem like it's their problem, since Chrome handles it fine. Just some interaction with JS memory allocator.
Chrome's is more greedy in defragmenting, which means e.g. getting many millions small objects interspersed with large objects is much slower, but doesn't "leak" memory.

    
    

    
  
orphan nodes sure look like a gmail problem.

(Google Reader had massive problems related to keeping otherwise dead native objects alive by having
references to them in JS)

    
    

    
  
There aren't that many orphan nodes, if any, but JS is consuming quite a bit of memory - about 80 MB or more, depending on the page.

    
    

    
  
I'm having this issue as well. As soon as I start up Firefox (with Gmail loading being that I have it as an app tab), Gmail starts using over 100MB of memory instantly. It sometimes builds up over time (seen 180MB few days ago at work, which is on Mac, at home is on Ubuntu), but sometimes it decreases as well. After 15 minutes of Firefox running, it's down from 110MB to 63MB.

If there is anything I can do to help by monitoring or something like that, please let me know. I am aware that I'm responding on an old report, but I have been having this problem for over a month now I think, so I decided to look for it and stumbled apon this ticket.

100 MiB of memory for Gmail doesn't necessarily indicate a problem. In a fairly new session I have similar numbers:

Gmail just tends to use that much memory. The original issue here was the large amount of orphan nodes, which do indicate a potential problem.

If you can visit about:memory, hit "measure", and then copy and paste the gmail data the same as I have above, that might be helpful, though I suspect in your case there's nothing really to act on.

    
    

    
  
You are right, I doubt there is something big going on. The memory on orphan nodes is very low as well (0.47MB, if I'm looking at the right statistic), so it definitely seems that issue is gone.

I've seen this over the last two weeks twice again. The GMail tab is consuming ~1.6GB of memory now, and each time when I switch to a different tab the CC/GC seems to be run on the GMail tab that is causing a delay of some milliseconds (indicated by a loading wheel) when switching back to that tab. Here a Firefox profile: https://share.firefox.dev/46v3yzK


Here a verbose memory dump:

Not sure if I had the DevTool's browser toolbox open which might indicate a relationship to bug 1689863?


Andrew, do you have an idea?


Flags: needinfo?(continuation)

    
    

    
  
Were you using recent Nightly? https://bugzilla.mozilla.org/show_bug.cgi?id=1863491 fixed a bad regression.



    
    

    
  
No, mine was Nightly 121.0a1 (20231112094805). So that is a revision from before that fix landed. I'll keep an eye on the memory usage. Thanks for pointing out!
