SpiderMonkey-115.5.0

[ken@…]

ff 115.5.0 now released. If it is true that only changes in js/src affect security issues in SpiderMonkey, then this is not a security update. The only change in js/src is:

 }

But I do not claim to understand javascript, nor how the pieces of firefox fit together.

This seems only improving crash reporting.
