It's a dark theme at nighttime and a light theme at daytime. Both modes are beautiful.

The nicest purple there is!

What I like is that it keeps the context menu options white when you right-click and the menu options are also fully white.

One suggestion for change: "Open Application Menu" at the top right is unfortunately in navy blue when it should also be fully in white.

A big advantage of this Firefox Alpenglow theme is that you can easily read the tab names and also the tab names on the Bookmarks Toolbar.

Thanks for making this Firefox Alpenglow theme available to all.
