Is "RTL Flow" on Firefox Add-ons Safe to Install?

voidksa2 · firefox · v1.0.1

RTL Flow is a powerful browser extension designed for users who read and write in Right-to-Left (RTL) languages like Arabic, Persian, Hebrew, Urdu, and Dhivehi. It solves the common problem of mixed text (English + RTL) misalignment and poor font rendering on modern websites. Key Features: * Smart Direction Fixing: Automatically detects and corrects text direction (RTL/LTR) paragraph-by-paragraph without breaking the page layout. Perfect for AI chatbots (ChatGPT, Claude), social media, and documentation sites. * Universal Support: Works on any website, including resistant Single Page Applications (SPAs). * Beautiful Fonts: Replaces default system fonts with high-quality, readable fonts optimized for each language (e.g., Tajawal for Arabic, Vazirmatn for Persian, Rubik for Hebrew, Noto Nastaliq for Urdu). * Custom Fonts: Upload and use your own local font files (.ttf, .woff) for a personalized reading experience. * Auto-Save: Remembers your preferences (enabled/disabled) for each website automatically. * Privacy-Focused: All processing happens locally on your device. No data is sent to external servers. Why install this extension? If you frequently encounter broken text alignment on the web—where Arabic starts from the left, or mixed English/Arabic text is jumbled—RTL Flow is the essential tool to fix it instantly. It provides a seamless, native-like reading experience.
