1783778 - Unconstrained memory use from Google Pixel 6a website

Status: RESOLVED DUPLICATE of bug 1785041

(Web Compatibility :: Site Reports, defect)

Description

[Asif Youssuff]

Attachment: google-pixel-6a.gz

From: https://www.reddit.com/r/firefox/comments/wjoodd/firefox_ram_issue_caused_from_google_pixel_6a/

Steps to reproduce:

1. Navigate to: https://store.google.com/product/pixel_6a?hl=en-US

What happens:

Page doesn't seem to finish loading and memory usage goes up rapidly. Within 2 or so minutes, my OS reported that the content process was using 5GB - the report on reddit said 10GB - I'm sure I could have waited longer to get to that point.

Memory report attached.

Tested on release Firefox, but the issue seems to happen on Nightly as well.

The page does not finish loading and high memory usage.

Lots of "GloballyAutoplayBlocked" DOM events. Maybe the page is reacting badly and keeps retrying to play some audio/video.
