Web Page Fixer: RTL/LTR EN

🌐 Web Page Fixer: RTL/LTR (Smart RTL for LLMs)

A powerful, privacy-first, zero-lag browser extension designed to fix Right-to-Left (RTL) text formatting (Arabic, Hebrew, Persian) on modern AI streaming platforms like LM Arena, ChatGPT, Claude, and Google AI Studio.

Powered by Manifest V3, this extension effortlessly handles deeply nested React Virtual DOMs, dynamic streaming chunks, and iframe injections without breaking native layouts or draining CPU performance.

✨ Core Features

• Smart RTL Mode: Dynamically forces dir="auto" specifically on chat bubbles and paragraphs, letting the browser naturally align mixed RTL/LTR text without altering the root <html> direction.
• Code Block Immunity: 🛡️ Strictly protects <pre> and <code> blocks, ensuring your syntax highlighting and left-to-right code alignments remain perfectly intact.
• Extreme Performance: Implements a highly optimized 250ms debounced MutationObserver. It waits for React/Gradio to finish rapidly streaming text chunks before safely sweeping the DOM, saving your CPU and battery from infinite render loops.
• Edge & Safari Iframe Support: Utilizes match_about_blank and localized fallback intervals to ensure the extension reliably docks into deeply nested, about:blank streaming side-by-side iframes (crucial for LM Arena).
• Zero-Layout Breakage: Aggressively untangles stubborn CSS frameworks (like Tailwind .prose) using nuclear specificity so sidebars, absolute buttons, and flex row margins don't overlap when flipped.

🛡️ Absolute Transparency & Permissions

We believe in 100% open-source transparency. This extension collects ZERO user data, runs no analytics, and connects to NO external servers.

To function seamlessly, the extension requires the following permissions in manifest.json:
- "storage": Used exclusively and locally on your machine to save your toggle preference (RTL/LTR/Smart) per website domain.

💻 Tech Stack

• JavaScript (Vanilla JS): Zero external libraries. Pure, lightning-fast DOM manipulation.
• Manifest V3: The latest, most secure standard for browser extensions.
• CSS3: Nuclear-specificity injection to override rigid framework alignments.
