Qwen RTL Toggle by Linux Fixes

Qwen RTL is a lightweight Firefox extension that adds full Right-to-Left (RTL)
text support to chat.qwen.ai, making it fully usable for Arabic and Persian speakers.

What it does:
When you click the extension icon in your Firefox toolbar, it instantly applies RTL
direction to all message bubbles, chat input fields, and text areas on the Qwen chat
interface. Click again to turn it off and return to the default Left-to-Right (LTR) layout.

How it works:
The extension injects a small CSS file that sets the text direction to RTL on all
relevant elements, while keeping the overall page layout intact so the UI does not break.
Your RTL preference is saved per tab using Firefox session storage, so if you refresh
the page, RTL mode is automatically re-applied without you having to click the button again.

Key features:
- One-click toggle — turn RTL on or off instantly from your Firefox toolbar
- Per-tab state — each tab remembers its own RTL setting independently
- Auto re-inject — RTL is restored automatically after page reload
- Non-destructive — only affects text direction, never breaks the page layout
- Minimal permissions — only requests access to chat.qwen.ai, nothing else
- No data collection — the extension does not collect, store, or transmit any personal data

Permissions used:
- tabs — to apply changes to the current tab only
- scripting — to inject the RTL stylesheet into the page
- storage — to remember the RTL state per tab during your session

Who is this for:
Anyone who writes in Arabic or Persian on Qwen and wants a proper RTL reading and
writing experience on Firefox without any manual configuration.
