We have something for you to try if you are able, to get your feedback. https://firefox-ci-tc.services.mozilla.com/api/queue/v1/task/cS4TP33hS7yHdUx2l1zlyQ/runs/0/artifacts/public/build/target.dmg which is 78.5.1 plus a patch. It will display as version 78.6.0 although some places might refer to it as "Thunderbird Daily" because it is a test build.
