simpleBlock is a free Chrome extension developed by newbigi. It falls under the category of Browsers and is specifically listed as an Add-ons & Tools subcategory. This efficient ad blocker is designed to be easy on CPU and memory.

Based on uBlock Origin, simpleBlock offers a similar ad blocking experience with one notable difference. Instead of a whitelist-site button, the popup UI features a global switch on/off button. This caters to users who prefer using a global switch instead of whitelisting specific sites.

The performance of simpleBlock is on par with uBlock Origin, neither being faster nor slower. There are no additional features or tracking present in this extension. The only difference lies in the switch button, making it a straightforward and reliable ad blocker for Chrome users.
