Made the extension types appear indented in the TOC, and added a header above all of them, also for the TOC
__TOC__
=== Supported extension types ===
The following extension types are supported in from Thunderbird 63 and beyond:
==== WebExtensions ====
This is the same type of addon that Firefox currently uses. For a general introduction, see [https://developer.mozilla.org/docs/Mozilla/Add-ons/WebExtensions WebExtensions] and [https://developer.mozilla.org/docs/Mozilla/Add-ons/WebExtensions/What_are_WebExtensions What are WebExtensions].
* And more, check meta-{{bug|1396172}}
==== Bootstrapped extensions ====
Bootstrapped/restartless extensions with an install.rdf manifest. The code to handle bootstrapped extension and install.rdf has been moved to comm-central in {{bug|1510097}} and should be stable now. Important: Bootstrapped legacy extensions continue to work without a manifest.json file and will in fact break if you add that file.
==== "Legacy" XUL extensions with overlays ====
"Legacy" XUL extensions with overlays are still "somewhat" supported in Thunderbird 63 and beyond. An inbuilt overlay loader will load XUL overlays for extensions but may cause graphical glitches or malfunctions. We're tracking this in {{bug|1476259}}.
