1414661 - Memory usage in Quantum

Status: RESOLVED INCOMPLETE

(Core :: General, defect)

Description

[lewbjob]

Attachment: memory-report.json.gz

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:52.0) Gecko/20100101 Firefox/52.0
Build ID: 20100101

Steps to reproduce:

* Firefox 57.0b14

Addons:

* Cookie Auto Delete
* Decentraleyes
* UBlock Orgins
* Privacy Badger
* HTTPS Everywhere


Actual results:

* 207.70 MB (100.0%) -- explicit
* 134,217,727.94 MB (100.0%) -- address-space

I have tried new profile. With 2-3 tabs open memory will get over 1 gig of usage with cpu above 50%. I'm also getting a lot of Page taking a long time to load messages asking if i want to wait or kill.


Expected results:

Memory usage shouldn't be over a gig with under 4 tabs

This is a very reasonable and typical value.

This tells you how much address space the entire system has, not how much Firefox is using.

Where did you get the "1 gig" measurement from?

I can believe that you are having performance problems, but judging from the memory report the memory usage is fairly reasonable.

I have the same issue, but it seems to be happening when i open several facebook pages with video. 
I also get at the same time an error of memory shortage from windows.

Disabling e10s seems to partially solves this (browser.tabs.remote.autostart to false). 
Another fix is to set dom.ipc.processCount and dom.ipc.processCount.webLargeAllocation to 2. 

By applying one of these 2 fixes, pages keep loading, rather than giving up.

If you go to the windows task manager (ctrl-alt-delete), and look at the background processes. You get one process of 800mb for firefox.exe next to several other firefox.exe background processes. I got 2gb in my pc and i get memory shortage errors. 

This might be the memory consumption that [e-mail] repported.

That number reaches over 50% CPU usage and over 1,000 mb with less than 4 tabs open. None of which have video content of any kind. Have to go through about:memory to release ram from closed tabs. Also have to frequently close Firefox through Task manager due to freezing. Have 4gig of ram installed.

On my pc, i have the same issue. 
I do see more problems with addons like ghostery, uBlock, privacy badger or disconnect. When I try to close my browser, the memory keeps locked on shutdown and firefox only closes after several seconds. So this might be interesting route to investigate.

First I saw the issue with ghostery and I tried to replace it with privacy badger or disconnect, but all exhibit issues with memory 'locking' on shutdown.

For adblocking, Adblocker Lite seems to exhibit the least issues with memory usage.
I have not found an alternative for ghostery. Ghostery doesn't exhibit these issues on chrome.

Steps to reproduce:
1. open several pages in firefox on a pc with 2 gigabyte in firefox with ghostery (or privacy badger or disconnect)
2. open task manager and look for background processes

Result
Firefox keeps running several seconds when addons are installed

Expected
Background processes firefox.exe close directly / reclaim memory.

I opened a separate issue for the video issue with number 1421186.

And without the addons?
