After TB update to 52.1.1 this add-on started to cause TB to crash when opening a new (or reply) mail window (editor).

This review is for a previous version of the add-on (1.0.3). 

Thank you for using mmsAutoCorrect. I am running TB 52.1.1 on my own laptop (Windows 10 64-bit) without crashes. I have been made aware that the custom word replacement hasn't worked for a while, apparently because Mozilla changed the file layout or somesuch, the solution to which is, unfortunately, above my pay grade (ok, ok, above my knowledge of the internals of TB). I welcome any help in duplicating the crash problems, and/or to solving any problems with this add-on. TBH I adopted this orphan project and have not been able to contact the original developer, so I am at a bit of a loss on fixing it.
