Recompile Chromium with JavaScript, Cookies, Notifications and Profiles disabled, with Claude's help

I recompiled Chromium with JavaScript, Cookies, Notifications and Profiles disabled. No cookies, no cookie banners, no tracking, no nonsense. A nicer Lynx with a GUI.

Here are the steps to follow, naturally, on Linux - in my case a Fedora based Toolbx container:

Install build dependencies:

sudo dnf install gperf flex bison clang lld llvm ninja-build nodejs npm python3 java-11-openjdk-headless libdrm-devel libxkbcommon-devel mesa-libgbm-devel pango-devel cairo-devel alsa-lib-devel cups-devel dbus-devel gtk3-devel nss-devel libXtst-devel libXdamage-devel

Clone and initialize depo_tools:

cd ~
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
export PATH="$PATH:$HOME/depot_tools"
gclient

Clone Chromium:

mkdir chromium && cd chromium
fetch --no-history chromium

Generate build config:

cd src
gn gen out/Default --args='is_debug=false is_component_build=true symbol_level=0 blink_symbol_level=0'

Write this patch generated with Claude's Opus 4.5 help to a file named decrapify.patch:

Apply the patch:

git apply --check decrapify.patch

Compile:

autoninja -C out/Default chrome

It will take a while. Until then have a quick look at the performance of my water cooled 7950x under load:

Open the browser:

out/Default/chrome

DevTools will be disabled as that feature is JavaScript based. Enjoy a clean and safe Internet.
