White Background Enforcer per nickesc

Overview
White Background Enforcer (WBGE) is a small, open-source browser extension – made especially for Zen browser – that enforces (by default) a white background on transparent pages and pages that do not have a background-color set.

Options
The extension can be disabled and the color of the background can be changed using the extension's Toolbar Button or the extension's Preferences tab in Add-on Manager (about:addons) > Extensions > White Background Enforcer. Some websites may need cutom rules for WBGE to function how you would like. Custom rules are documented in the extension's README on GitHub.

Privacy
WBGE does not collect or track any data.
