I love that #icecat now ships with privacy redirects to #invidious (privacy-preserving youtube front-end), #nitter (same but for twitter), #openMaps, #simplytranslate (instead of #google maps & translate), #wikiless (instead of #wikipedia), and more now.
It's fast. I usually don't even notice I'm on a proxy site, except when I watch entire Youtube playlists without seeing a single ad. This is a big improvement not just to icecat's set of features, but also it's approach to encouraging non-compliance with the biometric surveillance industry. I used to essentially turn icecat back into firefox by disabling most of its features to ensure no websites get broken (so that I can use picture-in-picture on #guix), but now I'm getting way less broken websites and more alternative front ends to predatory websites that I'm going to visit for discourse regardless.
Also hot tip, if you watch videos on invidious instead of youtube, it will actually recommend helpful videos to you, because rather than suggesting intellectual dark web videos for years to no avail, you get stuff like "The Nanopass Framework As a Nanopass Compiler", "#Lean meets #compilers", or whatever you're into, no matter how obscure, stuff you would have had to skim through completely unrelated Lex Friedman suggested content to find otherwise.
