Photophobia is dynamic theme that let you change the Hue, Saturation and Brightness of the Texts and Panels.
If you have sensitive eyes you will love this theme.
What that theme solve:
- Sometimes the light text for dark backgrounds is too bright, especially at night.
- Some people like a bluish dark theme, some others prefers redish.
- Sometimes you're on a dark website and firefox is very bright and hurts your eyes.
Static Version: PhotophobiaI recommend you install the static version as a base, or you can set the default dark theme, if you dont set a dark theme as a base you firefox will flicker lighter when opening.
I hate that!.
