## Review summary

Users appreciate the add-on's simple WebSocket client functionality but report usability issues such as the window closing too quickly after sending messages, lack of support for multi-line input, and poor handling of connection errors. Several users note the absence of options to open the client in a new tab or pop-out window. Additionally, some find it unclear how to start or access the interface from the Firefox UI.

### Pros

- Simple and clean interface for WebSocket connection testing.
- Provides a basic WebSocket client functionality within Firefox.

### Cons

- Window closes immediately after sending, preventing copy-paste of messages.
- Lack of option to open client in a new tab or pop-out window for better usability.
- Does not handle closed or invalid WebSocket connections gracefully.
- Request input area is too small (single-line), making it difficult to edit multi-line data like JSON.
- Unclear how to launch or access the add-on interface; no menu link or obvious UI element.
