Patch

Here's a patch. It was pretty straight-forward for the most part.

I made one minor improvement: warnings now have "PAC Execution Warning" prefix instead of "PAC Execution Error".

I manually verified errors and warnings still appear in the browser console as before.

Not needed: all the places that check that option also check autoJSAPIOwnsErrorReporting.

>   nsresult Init()

While you're here, can you change the JS_InitStandardClasses callsite to check the return value?

Also, don't you need to put the AutoPACErrorReporter before the JS_NewGlobalObject call?  I'd expect that JS_NewGlobalObject can throw OOM...  Alternately, we could just JS_ClearPendingException if JS_NewGlobalObject fails.  That might be simpler, because it's not clear what AutoPACErrorReporter would do if we're in the null compartment.

> ProxyAutoConfig::GC

Do you really need AutoPACErrorReporter here?  JS_MaybeGC can't exactly throw or report an exception.

r=me with the above fixed.
