debug.SKILL.mdname: debug description: Show console errors and failed network requests argument-hint: [console|network|all] disable-model-invocation: true
/firefox-devtools-mcp:debug
Displays debugging information from the current page.
Usage
/firefox-devtools-mcp:debug # Show all (console errors + failed requests) /firefox-devtools-mcp:debug console # Console messages only /firefox-devtools-mcp:debug network # Network requests only
Examples
/firefox-devtools-mcp:debug /firefox-devtools-mcp:debug console /firefox-devtools-mcp:debug network
What Happens
- `console`: Calls `list_console_messages` with `level="error"`
- `network`: Calls `list_network_requests` with `statusMin=400`
- `all` (default): Shows both console errors and failed network requests
Requires Firefox to already be running and on the page you want to debug. If Firefox is not running or is on about:blank, call `navigate_page` first.
