Many thanks for making this compatible with FF Quantum. FoxClocks is an extension I find really useful in my work - shows me the time for several of my colleagues around the world in a glance.
HOWEVER: it turns out the new status bar function messes up several webpages I commonly use, so I disabled it. Also, it’s a pity that there is no localized version (yet?). I hope that will return; it took quite a bit of effort back in the day to get all the translations right, and it would be a shame if the effort (and not just mine) is now wasted. So, four stars for now, because it’s still awesome!
