The picture beyond Thunderbird version 60 is rather uncertain, given the continued high rate of change in Firefox platform code. We will work with add-on authors in the coming months to determine a viable post-60 add-on strategy. Here are some general thoughts. | The picture beyond Thunderbird version 60 is rather uncertain, given the continued high rate of change in Firefox platform code.

Work has been undertaken to keep supporting legacy add-ons "somewhat" in Thunderbird 63 and beyond. We implemented an overlay loader that will load XUL overlays for add-ons but may cause graphical glitches or malfunctions. We're tracking this in {{bug|1476259}}. | * Work has been undertaken to keep supporting legacy add-ons "somewhat" in Thunderbird 63 and beyond.

* Legacy add-ons must replace install.rdf file with a WebExtensions style manifest.json file, which includes the key "legacy" set to true. See Lightning as an example https://hg.mozilla.org/comm-central/rev/e81f4b59a00a7d3e18d50fd3851ecbd47762a186#l2.5. | |||

* The general idea for TB 68 ESR will be to make add-ons restartless, although the replacement for restartless add-ons in TB 68 isn't yet clear, or to WebExtensions, where we still have to define the interface. Further reading on restartless add-ons: | |||
