[v1.5 (December 15, 2025)] - In v1.4, we fixed the detection of whether to "Edit as New Message," but we found cases where it was not correctly detected. Therefore, we have removed this feature and fixed the issue so that templates are always inserted when creating a new message.
[v1.4 (December 13, 2025)] - Fixed an issue where inline images disappeared in Thunderbird 143 and later.
- Fixed an issue where a Thunderbird upgrade failed to detect whether to "Edit as New Message," resulting in unintentional template insertion.
[v1.3 (December 13, 2025)] - Fixed an issue where switching IMEs in the email composition screen did not work in Thunderbird 143 and later, making it impossible to input Japanese characters.
- Fixed an issue where templates were sometimes not inserted when forwarding.
