Firefox extension to obfuscate web page text

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

    Firefox addon to quarantine a tab to use offline with private data2023 · ▲166

    Introducing QuaranTab: Companion extension to quarantine tabs so you can safely use them offline with private data I find myself wanting to use online format parsers to quickly decode that production JWT or decode a base64 Authorization header but cannot trust these websites to not leak my information. I thought to myself if only I could cut-off network access to this site, use it offline, and then throw away all browsing data. So I created an extension just for that.
