Steps to reproduce:

https://support.mozilla.org/en-US/questions/1208008

I've noticed a huge spike in Firefox Quantum's memory usage recenlty imgur.com/XCDtJy8 What do you think is the cause for this? Didn't install any new extensions or plugins, already ran scans with various antivirus/antispyware & registry fixer tools, they didnt detect any malware & fixed all registry issues. I also already cleared cache & cookies, saved data, refreshed & unistalled/installed Firefox Quantum multiple times, without improvement.

Normal usage until recently was about 300-500MB total, 50 MB per subprocess. Now is about 500MB PER subprocess (around 3-4 GB total) all the time. Is there a way you could look at some data or files from my Firefox installation to determine what is the cause for this memory usage increase? Maybe looking at the "about:memory" information to see what is making the processes use so much memory? I added the troubleshooting information to this question, and am willing to provide any other information you deem neccessary for troubleshooting purpose.

Thank you so much in advance, looking forward to hear from you!

Actual results:

I normally also have around 10-15 tabs open and from November to mid February the RAM usage would be in the 300-500 MB range. After the last Firefox Quantum & Windows update it is in the 3-4 GB range all the time. At least it doesn't slow down but I also think this is some sort of bug within the browser's code. Hoping that it gets fixed in the next release and would like someone to look at the technical info I automatically submitted with this Question & also my memory report file that I will provide on demand.


Expected results:

Firefox Quantum memory usage in 300-500 MB range instead of 3-4GB range.

Thank you for including the memory measurements in your bug report! It would be even more useful if you could also get a memory report when running in safe mode to see what the situation looks like without the extensions installed. Could you post that as well?

Hi, sure here it goes. Now in safe mode I noticed a decrease to around 1.3 GB used, 13 tabs open, 6 subprocesses running, around 250-300MB per subprocess.

Hi, sure here it goes. Now in safe mode I noticed a decrease in memory usage to around 1.3 GB, 13 tabs open, 6 subprocesses running, around 250-300MB per subprocess. Still high considering the 300-500 MB I used to get total with 15 tabs and full plugins running.

Comment 5

[CyberChaosCrew]

I see the status of this bug report has been changed to "UNCONFIRMED bug with no priority". Could you not identify the cause of the increased memory usage with the memory reports?

Comment 6

[CyberChaosCrew]

I would like to know if the memory reports I submitted are still being analyzed and if not If you have any suggestions for the issue I'm experiencing with Firefox Quantum. 

I'm getting around 250MB memory usage with Chrome with similar plugins & the same ammount of tabs open & processes running. I like Firefox and have been a long time user but if the situation doesn't improve I will have to import my profile into Chrome and move on.

Moving to Core::General so that people more familiar with the platform can take a look. Could you post the contents of about:support as well? I wonder if there is something unusual about your configuration.

Comment 8

[CyberChaosCrew]

Sure, here it goes. 2 days ago I had to delete all local files and redo the installation of another CPU/Memory intensive program (XSplit Broadcaster) & I did the same for Firefox Quantum again. This other app's high CPU load issue was resolved, but Firefox still has high memory loads.

Each content process seems to be using ~300MB of GPU memory, so it seems like that's where your overhead is coming from. I'm not sure if this is add-on related, but you you might try disabling your extensions one by one to see if that helps.

It does help, if I start in Safe Mode with all extensions disabled the total memory usage will drop to around 1.3 GB for 15 tabs open, 6 subprocesses running (around 250-300MB per subprocess). But since November to February I used to get 300-500 MB I used total with 15 tabs and the same extensions running.

Thanks for the priority update. I'm still experiencing the reported issue with Firefox.
