Sometimes you might want to share a screenshot of the website you're on, without revealing the personal data that is visible at that time. With Obfuscate, you can make text unreadable without changing the structure of the web page. Hit the extension button or press Alt+Shift+O to activate for the current page. (Note that extensions can't modify the add-on website, so trying it on there won't work.) Credit for the original idea: https://chaos.social/@maris/108379386421123630
