无法使用。但估计是浏览器的问题。

Can you please add an option to be able to add a ':' after the hours plugin? Thanks!

I forked this and made it 12 hour format

https://addons.mozilla.org/en-US/firefox/addon/clock-hours-12/

The only addon that let's me put a READABLE clock in the top right corner of my browser (since Mozilla killed FoxClocks).
I just really wish you could set it to 12hr instead of 24hr.

Why did you make it with military time only, are you in the army or something. I guess you didn't know, for some strange reason, that most people want a 12 hr clock.

Exactly what I was looking for. Could do with customization, maybe font choices, but those are extras.
This is a clock that's simple and works. Even the hour/minute parts are separated, presumably to fit the extension icon size, but also allowing you to have a less precise "hours only" clock depending on how you prefer to manage your time.

If you're like me, and using this with a tab sidebar extension in full-screen, you can actually customize the Firefox toolbar (including the forward/back/refresh buttons), and have it sit above your tab sidebar! Simplicity wins!

Is it possible to make a 12 hour format option?

Can be updated switch mode(drak light) custom text color

The extension is great, but it lacks the shade change with a click!
