FPS extension Chrome Extension Analysis

Listing positioning

The extension positions itself as a lightweight tool for debugging website performance. It is marketed as a faster, more convenient alternative to the built-in Chrome Developer Tools for monitoring frames per second (FPS).

Inferred product pattern

Simple single-purpose developer utility for performance monitoring.

Review-backed pain points

Users frequently report that clicking the extension icon results in no visible change or counter appearing on the page. There are also complaints that the tool cannot measure frame rates above 60 FPS, rendering it useless for high-refresh-rate testing.

Observed feature gaps

Lack of support for high-refresh-rate monitors (above 60Hz) and a lack of compatibility with recent Chrome extension best practices/manifest versions.

Support

No specific support communication complaints, but users report the tool is effectively broken.

Reliability

Severe reliability issues; multiple users state the extension does not function at all and produces no output upon activation.

Privacy

No privacy or security complaints observed.
