Alice, can you please try again with the latest nightly? Because locally I cannot reproduce it anymore.

Alice, can you please try again with the latest nightly? Because locally I cannot reproduce it anymore.

The issue high cpu & memory(5GB/2min, 10GB/5min ...) is reproduced on Nightly132.0a1(20240924094722) on windows11 with new profile.

Profiler fails to display due to timeout error.

Reproduced the issue with Firefox 132.0a1 (2024-09-20) on Windows 10x64 by opening https://www.microsoft.com/en-us. The page will not paint and the memory will increase hanging the browser.
The issue si verified fixed with Firefox 132.0b5 on Windows 10x64, macOS 12 and Ubuntu 24.04. The page is painted as expected and no memory increase can be seen after some time.
