No RTL to RTL от Mohoom

No RTL to RTL is a lightweight Firefox add-on that automatically forces ChatGPT's interface to display in Persian (fa-IR) with a right-to-left (RTL) layout. It also applies the Vazirmatn font (by Saber Rasti Kerdar) for better readability.
The add-on works on chat.openai.com and chatgpt.com and requires no configuration.
