As the title states, I click the "Connect" button , ask the LLM a question, and it still says I need to click connect, even though I already did. I've attached a video recording.
Here's the error message :
[ { "type": "text", "text": "Error: No connection to browser extension. In order to proceed, you must first connect a tab by clicking the Browser MCP extension icon in the browser toolbar and clicking the 'Connect' button." } ]
