User Reviews

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.

Is Simple WebSocket Client Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Simple WebSocket Client requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Grants access to browser tabs, which can be used to track user browsing habits and history, presenting a privacy concern.
