Works really well, i wish there was something similar for battery percentage

This is the one that i search for.

For the users who cannot read "military" time, learn to adapt kids, the world does not revolve around you.

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!
