That's not what the bug says; it says that <b
class="moz-txt-star"><span class="moz-txt-tag">*</span>in-line<span
class="moz-txt-tag">*</span></b> preferences (the kind where
you see some options directly in the addon's details page in <a
class="moz-txt-link-freetext" href="about:addons"
moz-do-not-send="true">about:addons</a>) won't work anymore.
Preferences themselves should be fine, as should any add-on that
doesn't use preferences at all. I've written about a half-dozen
Thunderbird add-ons, and I think only one is actually affected by
this change.

the mozilla57/58/59 period and some changes to JS syntax that
most add-ons will require some sort of update to their code.
That will distinguish the "maintained" add-ons from the
"unmaintained" add-ons some/most of which will stop working.</tt></p>
