Chrome Extensions That Actually Speed Up Your Browser
4 min read · Updated 8/25/2026
Most extensions slow Chrome down. These are the rare ones that make it faster — tested and ranked.
The Paradox
Extensions add code to every page, which usually slows things down. But a few well-designed ones save more than they cost.
The Speed Winners
- **[OneTab](https://singletabbrowser.com/extension/onetab)**: collapses dozens of tabs into a list and reclaims gigabytes of RAM. - **[uBlock Origin](https://singletabbrowser.com/extension/ublock-origin)**: blocks ads and trackers, so pages load with far less junk. - **Tab Manager Plus**: lets you close and restore tabs from a keyboard-first popup. - **Session Buddy**: recovers crashed sessions without restarting the browser.
The Hidden Culprits
- Extensions with content scripts that run on every page. - Multiple ad blockers running together. - Outdated extensions with memory leaks.
The Rule
Audit your extensions monthly. If you haven't used one in 30 days, remove it — every extension you keep costs performance.
