Status: NEW

(Core :: XPCOM, enhancement)

Description

[:Gijs (he/him)]

STR:

1. Add something like:

component {18269616-1dd2-11b2-afa8-b612439bda37} components/iamnothere.js
contract @mozilla.org/iamprettycool;1 {18269616-1dd2-11b2-afa8-b612439bda37}
category profile-after-change m-reallyiamprettycool @mozilla.org/iamprettycool;1

to chrome.manifest

Actual results:

Error in your error console saying:
"While creating services from category 'profile-after-change', could not create service for entry 'm-reallyiamprettycool', contract ID '@mozilla.org/iamprettycool;1'"

Expected results:

Errors in your error console saying:
"When trying to load component with CID '{18269616-1dd2-11b2-afa8-b612439bda37}', Firefox could not find the file 'components/iamnothere.js'. Check that the path is correct"

"While creating services from category 'profile-after-change', could not create service for entry 'm-reallyiamprettycool', contract ID '@mozilla.org/iamprettycool;1'. Are you sure the component was loaded successfully? Earlier errors might indicate what went wrong."

(note that if your component has JS errors, they will also be displayed earlier)
