How to Make Chrome Run Faster By Blocking Ads
Patrick Bushe · May 1, 2026
Ads and tracking scripts don't just take up space: they download code, run it, and often keep running while the page is open, which uses CPU, memory and battery. Ultimate Adblocker stops them before they load, using Chrome's built-in blocking engine, so Chrome has less to download and less to run. On ad-heavy sites the difference is large; in one test, weather.com's homepage went from 842 requests to 125 with the extension on. If Chrome is still slow with many tabs open, its Memory Saver setting can put inactive tabs to sleep.
