firefox-153.0esr

[Bruce Dubbs]

New majore version.

[Xi Ruoyao]

I plan to switch spidermonkey to use mach instead of configure as in this version we cannot test the package with the latter.

[Xi Ruoyao]

Anyway spidermonkey needs to wait until gjs is adapted: ​https://gitlab.gnome.org/GNOME/gjs/-/work_items/740

[Xi Ruoyao]

Split spidermonkey to #23631 as it's unlikely to be included in the upcoming BLFS release.
