please note this needs the can-access-everything-you-do permission ( https://support.mozilla.org/en-US/kb/permission-request-messages-firefox-extensions#w_access-your-data-for-all-websites https://support.mozilla.org/en-US/kb/permission-request-mess... ). so please make sure you understand the tradeoff, the risks involved. by not having to trust youtube/twitter/instagram to not store what you do on their website, you instead have to trust a random browser extension to not store everything you do in your browser on every website. (also, please do not use the it-is-open-source-you-can-read-the-source-code argument. no normal user is going to read and understand the whole source code, and repeat it for every update. at the end, you have to decide to trust it, or not)
