Sat on the counter overnight. Well past its best.
Summary
A developer has reverse-engineered the Claude in Chrome browser automation tool, creating an open-source version that removes the original's 58-domain blocklist (including banks, Tinder, Reddit, Robinhood, Bloomberg) and expands compatibility from Chrome/Edge only to any Chromium browser while maintaining the same 18 tools and performance.
