@Medvezhonok, thanks for your reply. I didn't specify the OS, it's Ubuntu 16.04.2. After the update to 52.1.1 a couple of other add-ons also stopped working, but they are not causing TB to crash, this one does.

The crash report says: "MozCrashReason: ElementAt(aIndex = 3, aLength = 3)". The crash happens just after a "new mail" or reply editor window loads (i.e. the window just appears and TB crashes).

Thank you for your review. This has been fixed in version 1.0.5 which has been submitted for review by Mozilla. Email me if you'd like an advance copy.

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).

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.
