I’m attempting to update a non-bootstrap legacy addon (not one I wrote) to Thunderbird 63. (I already got it working in 60.) I’m following this:
I have replaced references to stringbundle with lines like:
var bundle = Services.strings.createBundle(…)
I get this console message (though not on installation - on restart):
ReferenceError: Services is not defined
I have tried adding this to the js files:
but no effect.
What do I have to do?
