User reviews

Users find Compat Report a valuable tool for checking browser compatibility and understanding required polyfills, appreciating its convenient and clear information. However, multiple reviews highlight performance issues like lag and freezing, lack of dark mode support, and interface clunkiness such as full tab reloads when toggling stylesheets. Users also desire filtering features to improve browsing compatibility problems. Overall, while the add-on concept is praised, improvements are needed for smoother and more user-friendly operation.

Pros

Provides clear compatibility information for websites across different browsers.
Helps identify necessary polyfills for modern CSS/JavaScript usage.
Better and more convenient than manually checking compatibility websites.
Concept and functionality are appreciated and considered valuable by users.
Generally works pretty well despite some clunkiness.

Cons

Lags and freezes frequently, affecting usability.
No support for dark mode; interface is white and clashes with dark themes.
Turning off stylesheets causes entire tab to reload, not just compatibility section, making interaction clunky.
Lacks filtering options to easily browse compatibility issues.
