Question for Smex.
Following your advice, I followed all the instructions to change the 6.4 plugin and install it in Thunderbird 147.0.1. Unfortunately, as Manuel wrote, when manually installing the changed plugin with the number changed to "147" or "148," a message appears saying that the add-on cannot be installed because it appears corrupted.
I debugged the error with the Thunderbird tool and received the following message:

An error occurred during the temporary installation of the add-on.
Error Information

File C:\Users\quicktext-6.4-tb.xpi does not contain a valid manifest

This means that everything was probably done correctly, as you wrote, but Thunderbird currently doesn't accept the changed file.
I've repeatedly checked the entry in the changed "strict_max_version" line: "147.*," and everything looks identical to the original after changing the number. Do you have any idea what this might be about...?

This user has a previous review of this add-on.

One of the best plugins for Thunderbird.
