Changes

* Add-on options (dialog or inline) not working in Add-ons Manager, only tab options work. Fix on the way in bug {{bug|1419145}}provides a menu item to access add-on options. '''That fix has landed on Daily 59 as of 2017-12-22.'''

* Dialog (1) and Inline (2) options were removed in {{bug|1414406}}. Thunderbird will not support that feature any more, only options in tabs (3) will work in the future. We're working on a fix in {{Bug|1419145}}now. Alternatively add-ons need to embed a WebExtension to display inline options [https://developer.mozilla.org/Add-ons/WebExtensions/Embedded_WebExtensions][https://developer.mozilla.org/Add-ons/WebExtensions/manifest.json/options_ui]. This should be working now that {{bug|1418914}} has been fixed.

'''Suggestion for add-on authors wishing to be compatible with Thunderbird 59: WaitGo, go, go!''' The fix for {{bug|1414398}} (see abovedefault preferences) has arrived (2017-12-12). and {{Bug|1419145}} will provide a (menu to access add-on options and to make add-on , tab options (3) work again) has arrived (2017-12-12 and 2017-12-22). {{Bug|1418914}} has been fixed and then inline options can be achieved via an embedded WebExtension. We will prepare a sample of how this is done in early 2018. All add-ons compatible with TB 58 beta should also be compatible with TB 59 Daily.
