Hector Martin 434abe24fa extra/firefox: Fix regression on aarch64 (98.0.1-1.1) 
Firefox 98+ fails to draw its window on aarch64.
Upstream: https://bugzilla.mozilla.org/show_bug.cgi?id=1757571

Also add a hack to remove the psutil version cap, since otherwise it
fails to build with the latest python-psutil version (for no reason).

Raw Blame History

Description: Revert the upgrade of crossbeam-* crates that happened in Firefox 98.0,
which resulted in a regression on arm64 where the browser wouldn't draw its window.
This is a temporary measure until the exact cause of the regression is identified and fixed.
