- Compatibility: Compatible with Thunderbird 128.* through 137.* (and incompatible with Thunderbird 115 and earlier).
Changes relative to 0.6.2:
- #262 : In some cases, Thunderbird refuses to let our code work due to a hardening of the "content security policy" constraints. We now work around that by meeting the stricter constraints without a change of functionality.
Unresolved Thunderbird compatibility issues
Despite being generally compatible with the newer versions, some serious outstanding issues do remain, which I have not (yet) been able to resolve:
- The toolbar menu-button: TB developers broke the main toolbar, and the new "unified toolbar" is difficult to get buttons onto. How to do so is not documented. The code seems to shut out regular extensions, not allowing addition of more buttons except through a tightly controlled and limited mechanism which straightjackets webextensions. Typically hostile design.
- Folder context menu items: Multi-folder selection works again in Thunderbird since v128, but - it hides all context menu items for multi-folder selection which it doesn't know about; and leaves no hooks for making them visible again, so our context menu items get wiped away.
