Really nice and useful extension, especially the compact view.

4 stars, this addons is what I need in full screen mode. However, the font is small and I want little bigger.

I am using your addon and I like it. But, please, prepare for Firefox 57. I like seeing time in Firefox. Thank you for your efforts.

Does what it says, it's very simple and small. the only option available is to change the color.

the term "fullscreen browser use" might be misleading to "display the window in full screen (f11)", but it does what it says: the browser in fullscreen, means no Windows(OS) toolbar, so it's okay.

A nice little addon, but hard to read as the space it occupies is that of a simple icon.

Minimal. Nothing more than the time on the toolbar. Thanks!
