for some reasons, I can not see and edit "URLs in the sidebar" in the options. -Update- Received a prompt response from the creator, and my specific issue is resolved.

I'm switching over to this extension from the native Firefox AI Chatbot. Here I can add any chatbot I prefer, let alone any other web resource. Thank you for a simple, easy-to-use, and practical tool.

Is Universal Sidebar 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.

Universal Sidebar does not require any sensitive permissions.
