The extension can be activated by clicking the extension icon on your browser toolbar or by right-clicking the page you are on and selecting the extension's menu item.

- You can use this extension to clear your cache to prevent [cache fingerprinting](https://www.usenix.org/system/files/sec19fall_shusterman_prepub.pdf)
