1830338 - Hight memory usage on 112.0.2

Status: RESOLVED INACTIVE

(Core :: Performance: General, defect)

Description

[an.smodlev]

Attachment: memory-report.json.gz

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:109.0) Gecko/20100101 Firefox/112.0

Steps to reproduce:

nothing, no tabs or 1 youtube tab

Actual results:

Hight RAM usage: 1gb and other FF services eating memory too

Expected results:

it would be cool if FF ate not so much, it seems to me that there were no such problems before.

Now this is just an example, but when I develop an application in FF, I simply do not have enough RAM on a working computer with 16GB

The memory usage in the report you attached doesn't look like it is super high. There's a lot of heap-overhead which does suggest it used to be much higher.

This also suggests it used to be higher:
587.50 MB ── resident
1,049.19 MB ── resident-peak
1,112.14 MB ── resident-phys-footprint
436.05 MB ── resident-unique

I can't tell what the problem might be with this memory report.

I just came here to report this bug myself.
I already closed and opened the browser again because it turned useless, without making a screenshot, but memory use was above 12 GB with 5 tabs of Reddit and a couple of small wiki pages open.

Different platform from the original poster's.

Please file a new bug for your issue. It is impossible to tell whether you are experiencing the same issue or a different one without more information. There are many possible causes of memory leaks in Firefox, and putting more than one report together in a single bug will only confuse things. Thanks.
