2007800 - DoS by memory exhaustion that continues to run after closing tab

Status: UNCONFIRMED

(Core :: Performance: Memory, defect)

Description

[hotaru]

Attachment: gecko_iframe_DoS.html

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:146.0) Gecko/20100101 Firefox/146.0

Steps to reproduce:

1. open the attached file.
2. close the tab.
3. check memory usage of Firefox.

Actual results:

Firefox continues to use more and more memory over time despite the tab being closed, eventually exhausting all available memory.

Expected results:

closing the tab should stop the script, preventing it from continuing to consume more memory and freeing the memory that was consumed by the page.
