When i start for example live server extension and my html css extension is freezes directly and i have to restart extension host and then it freezes again
Hey, thanks for the report. I see the screenshot with Extension host became UNRESPONSIVE in the console. It looks like the extension host is freezing, not Cursor itself. From the symptoms, it’s usually a third-party extension doing heavy synchronous work and blocking the host. Live Server and some HTML/CSS extensions are known for this.
Let’s try to find the culprit:
Disable Live Server and your HTML/CSS extension, reload the window with Developer: Reload Window, and check if the freeze happens again.
If you want to automate it, run Help: Start Extension Bisect. It’ll use a split test to find the problematic extension.
When it freezes, open Developer: Show Running Extensions. The extension marked as unresponsive is the cause.
As a replacement for Live Server, I’d suggest trying Microsoft Live Preview ms-vscode.live-server. It’s maintained and usually more stable.
Let me know what bisect finds, then we’ll know if we should dig into an extension issue or a Cursor issue.
Great, so we found the culprit. Live Server ritwickdey.LiveServer does heavy synchronous work and blocks the extension host. The same would happen in regular VS Code too, so it’s not something specific to Cursor.
As an alternative, try Microsoft Live Preview ms-vscode.live-server instead. It’s maintained and usually more stable. If you really need Live Server, keep it disabled when you’re not using it so it doesn’t freeze the host.
Let me know if Live Preview works fine or if anything else comes up.
