Browser extensions are underrated productivity tools. A short list of well-chosen ones can speed up debugging, accessibility checks, responsive testing, and reference lookup.
Categories that matter
- Inspect & debug — clearer CSS/DOM tooling
- Responsive & device testing — validate layouts quickly
- Accessibility — catch contrast and ARIA issues early
- JSON / API helpers — read responses without friction
- Capture & clip — save references into your notes system
Your ideal set depends on your stack. Build a personal toolkit from daily use rather than installing twenty extensions you never open.
If you have a favorite extension, keep notes on why you use it — that list becomes gold when setting up a new machine.
