uBlock Origin is an efficient, wide-spectrum content blocker browser extension for Chromium-based browsers and Firefox. It blocks ads, trackers, and other unwanted web content using CPU- and memory-efficient filtering.
Use cases
- block ads in my browser
- stop websites from tracking me
- speed up page loads by removing ads
- block annoying popups and banners
- filter unwanted content on firefox
- reduce memory usage compared to other ad blockers
When to choose
- you use Firefox, Edge, Opera, or another Manifest V2-capable browser and want a fast, free, open-source ad blocker
- you want fine-grained control over filter lists and dynamic filtering rules
- privacy and low resource usage are priorities
When to avoid
- you use Google Chrome after Manifest V2 removal, where uBlock Origin is no longer supported (use uBlock Origin Lite instead)
- you need a Thunderbird-supported version that is actively updated
