10 Modern Browser Extensions Every Developer Should Use in 2025.

A few months ago, I realized my browser was more cluttered than my code comments. Too many tabs, no organization, and a lot of time wasted. That’s when I decided to do something about it.

The result? These 10 extensions that transformed my workflow. Let me share them with you – and yes, these actually make a difference.

1. VisBug

You know when you’re debugging a UI, and it feels like you’re playing whack-a-mole with CSS? VisBug fixes that. Tweak spacing, fonts, and layouts right in the browser. Saves time, sanity, and your keyboard from getting smashed.

2. React Developer Tools

If you work with React, this is your lifeline. Peek into component hierarchies, props, and state without breaking a sweat. No more guessing what’s re-rendering and why.

3. Postman Interceptor

APIs are the backbone of everything we build. Postman Interceptor lets you capture network requests and debug directly from your browser. It’s like having X-ray vision for your backend.

4. Dark Reader

If you’ve ever stared at a blinding white screen at midnight, you need Dark Reader. Instantly turns any website into dark mode. Your eyes will thank you. (Your designer friends might not.)

5. Web Developer

This one’s old-school, but still a powerhouse. Disable JavaScript, validate CSS, resize the viewport – it’s the all-in-one tool for frontend devs.

6. JSON Formatter

Reading minified JSON is like trying to read a book in a language you don’t know. JSON Formatter cleans it up, making it readable and colorful. Because who has time for squinting?

7. Wappalyzer

Ever wondered what tech stack powers a website? Wappalyzer breaks it down for you. Great for research or when you’re just being nosy.

8. Lighthouse

Performance. Accessibility. SEO. Lighthouse does it all. Run audits and get actionable insights in seconds. Think of it as your personal code reviewer (but less judgy).

9. Octotree

Navigating GitHub repos without Octotree feels like walking through a maze blindfolded. It adds a file tree view to GitHub, making it super easy to find what you need.

10. Pesticide

For the perfectionists out there, Pesticide outlines all elements on a page so you can debug layouts faster. Pixel-perfect design? Achievable.

Bonus: Tab Wrangler

We’ve all been there: 50+ tabs open, productivity sinking. Tab Wrangler automatically closes inactive tabs but keeps them retrievable. Declutter your browser, declutter your mind.

Your tools can either slow you down or level you up. These extensions belong in the second category. Try them out, and let me know which one’s your favorite.

    What about web tools for all the other good frameworks? It's sad

    You know what developer extension I wish someone would build? Firefox used to have a 3D page view where you could see what elements rendered in what order, stacked on top of each other. It was fantastic for quickly figuring out what's blocking a button from being click able or what's hiding an element.

    Great list of extensions—thanks for sharing!
    I'd like to suggest a few more that have significantly boosted my productivity:


    WhatFont

    Hover over any text to find out what font is being used — simple and effective.

    🔗 WhatFont


    Load Time

    Load Time offers an instant view of page load duration directly in your toolbar, plus a visual timeline of key navigation events. It’s especially helpful for web performance auditing and benchmarking.

    🔗 Load Time


    ColorZilla

    Eyedrop any color from a webpage, generate gradients, and explore advanced color tools.

    🔗 ColorZilla


    ModHeader

    Edit request headers (and responses too). Test APIs, simulate conditions, or debug CORS issues with ease.
