Auto RTL/LTR Switcher од Hamed Takmil

This extension automatically adjusts text direction based on the input language.

Many web forms default to left-to-right, which can hinder typing and readability for languages like Persian. As you type, if the extension detects Persian characters, it switches the direction to right-to-left; otherwise, it stays left-to-right.

Additionally, it provides two handy features:

Toggle Font: Switch the page font to Vazirmatn (from Google Fonts) and back to the default with a single click.
Toggle Direction: Manually change the entire page's direction (RTL/LTR) by clicking the extension icon.
