1858274 - Excessive Memory Consumption in Firefox

Status: RESOLVED INCOMPLETE

(Core :: General, defect)

Description

[eshesh594]

Attachment: memory-report.json

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/117.0.0.0 Safari/537.36

Steps to reproduce:

• I launched the Firefox browser.
• I opened a YouTube video in the browser.
• I continued to open two additional tabs in the browser.

Actual results:

• The browser immediately consumed approximately 400MB of memory upon launching.
• The memory usage increased to around 600MB when a YouTube video was opened.
• The memory usage continued to escalate with each additional activity, reaching up to 800MB and beyond.
• The Firefox Content process was observed to consume a substantial 1.6GB of memory in the Activity Monitor.

Expected results:

• The memory consumption of the browser should have been proportional to the number and complexity of the tasks being performed.
• The Firefox Content process should not consume such a substantial amount of memory under normal browsing conditions.

Not sure where to file this bug. Sounds like a general complaint about memory consumption, not media specific.

When was this memory report taken? As far as I can tell from the memory report, while it was taken Firefox was not using the amounts of memory mentioned in comment 1?

Redirect a needinfo that is pending on an inactive user to the triage owner.
:marco, since the bug has recent activity, could you have a look please?
