Theme font and size changer has disappeared from Thunderbird but not Firefox. Any idea what went wrong and how to fix it?
Do you mean it no longer appears as installed on your Thunderbird profile, or that it’s no longer listed on addons.mozilla.org?
It is no longer under the “Tools” option on the menu bar, but just now I
noticed that there is also a toolbar button which IS still there.Also it
is still listed on addons.mozilla.org.
I remember now that the addon “crashed” yesterday which must be the
cause of my problem. Thanks for responding
