Clean risk

Firefox Profiler sends user-triggered debugger traces from the active tab to Firefox Profiler.

When you start a trace from the toolbar or keyboard shortcut, Firefox Profiler attaches Chrome's debugger to the active tab and records loading, JavaScript execution, screenshot, URL, DOM content, and tab information. When you stop tracing, it opens Firefox Profiler and posts the collected profile there for viewing.
