Hi again, I thought I should at least try testing without any extensions enabled. That fixed it on xenial :-)
The offending extension was QuoteAndComposeManager 0.3.32.3 (1/16/13). Disabling this resolved the issue. My other extensions (especially Lightning, which is important to me) are OK. For me this issue can now be closed (extensions presumably not being part of 'the package'). However Daniele De Felice may still have issues. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1604394 Title: send button does not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1604394/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
