John, You say that "The bug is solved: Version 4.2 will no longer be shipped to TB91 users. Please re-enable auto updates." BUT what if QuickText 4.2 has already been automatically installed on TB91, as is the case for me. That is, the Signatures toolbar has disappeared. Thanks. Richard

This review is for a previous version of the add-on (4.2). 

I did not go into more details, as you said you had installed 4.1 manually on that system again, which is what is needed to be done.

Every TB91 system which got auto updated to 4.2 has to revert back to 4.1. The version 4.2 is for Thunderbird 102 and I made an error by shipping it to TB91 users. That is fixed now and will not happen again.
