## Description

CSS Reduce removes performance-killing visual effects from every website you visit — no setup needed.

Heavy CSS effects like backdrop blur, box shadows, animations, and parallax scrolling look cool, but they can bring old laptops, budget phones, and low-end devices to a crawl. This extension strips them out instantly, giving you smoother scrolling, lower CPU usage, and better battery life.

Two Modes:

• Lite — Disables backdrop-filter, blur effects, drop shadows, text shadows, CSS animations, and parallax. Keeps transitions fast (0.01s).

• Ultra — Goes further by removing all transitions, transforms, fixed/sticky positioning, background images, and border radius. Maximum raw speed.

Features:

• Works on every site automatically
• Runs inside iframes too
• Toggle on/off with one click from the toolbar
• Remembers your preference across sessions
• No data collection, no tracking, 100% offline

Perfect for old hardware, low-end Chromebooks, thermal-throttling laptops, or anyone who prefers speed over eye candy.
