This is probably a bit much to ask and I know you're busy but is there any way you could consider updating the legacy version to work again with 58/59 nightly? Mozilla is allowing legacy addons to continue in the unbranded firefox versions and I miss the toolbar icon that easily displayed the time and date. I'm not exactly sure but the recent break with foxclocks 4.3.2 might have had something to do with nsIPrefBranch changes. Thanks for your work.
