Functions as advertised, BUT (as many people have pointed out) this DESPERATELY needs a blacklist version as well as a whitelist version (as a college student who needs extended access to an ever-growing variety of websites, this would make it much more user-friendly, imo (also ditto to whoever said the option to import and export the white/blacklists)

Does not work on eBay, after a few seconds the site will freeze up and become unresponsive.

Nazmond·5 Aug 2024

Does what you expect it to do. Only have two complaints. The CPU usage is absolutely absurd, unless you have a strong PC you should probably not use this add-on Would be nice to have a blacklist, but as an alternative, you can block elements (or images) manually with an adblocker
