This vulnerability affects firefox < 115, firefox esr < 102.13, and thunderbird < 102.13. (
( CVE-2023-37201) cross-compartment wrappers wrapping a scripted proxy could have caused objects from other compartments to be stored in the main compartment resulting in a use-after-free.
( CVE-2023-37202) a website could have obscured the fullscreen notification by using a url with a scheme handled by an external program, such as a mailto url.
This could have led to user confusion and possible spoofing attacks.
