Firefox Theme uberAgent ESA
A theme based on the color scheme of uberAgent ESA, vast limits' endpoint security analytics product. The toolbar color has been chosen in such a way that the browser does NOT auto-select dark mode for websites.
Installation
The theme is available for installation at Firefox Add-ons.
Notes
Theme Color and Dark Mode
Firefox switches to dark mode automatically depending on the toolbar color of the browser theme. Firefox chooses dark mode independent of the related OS setting.
Header Image and Text Shadow
When a theme contains a header image (manifest setting theme_frame), the active tab's text gets a shadow, which makes it harder to read and generally does not look great. As of Firefox 95 there is no way to disable the text shadow except by not specifying theme_frame. That is the reason why this theme does not have a header image.
