10 Actually Useful Chrome Extensions (2026)

Most Chrome extension lists lead with ad blockers. Ad blockers are essential — uBlock Origin is listed here — but this list is about the extensions that change how you browse, develop, and communicate. Every entry solves a specific daily annoyance or unlocks a capability most users don’t know exists.

The Extensions

Vimium — Keyboard navigation for Chrome. Press f to see link hints, j/k to scroll, H/L for back/forward, / to search. Once muscle memory kicks in, reaching for the mouse feels slow.

OneTab — Collapses all open tabs into a single list, freeing up 95% of memory. Restore tabs individually or all at once. Essential when research sessions leave you with 40+ tabs.

GoFullPage — Captures full-page screenshots of any website with one click. Scrolling sections, infinite scroll pages — it handles them. Screenshots save as PNG automatically.

uBlock Origin — The best content blocker. Lightweight (uses less memory than similar blockers), highly configurable, and blocks ads, trackers, and malicious domains. Keep it simple — the default settings are excellent.

Tampermonkey — Runs user scripts on any website. Automate form fills, change page layouts, add keyboard shortcuts, bypass paywalls (ethically, for accessibility). With 100k+ scripts on Greasy Fork, it’s the swiss army knife of browser automation.

JSON Viewer — Formats and colorizes JSON in the browser. Syntax highlights, collapsible trees, and a search bar. Indispensable for API development — no more copying JSON into external formatters.

React Developer Tools — Adds a Components and Profiler tab to DevTools. Inspect React component props, state, and hooks in real-time. The Profiler identifies render performance issues.

Wappalyzer — Identifies every technology a website uses: framework, CMS, analytics, CDN, payment processor. One click reveals the full stack of any site.

WhatFont — Hover over any text on a page and it identifies the font family, size, weight, line height, and color. Essential for designers and frontend developers recreating designs.

Loom — Records your screen, camera, or both with a shareable link instantly. No file uploads, no export step. Record a bug report, code review, or walkthrough and share the link in seconds.
