let an agent drive your browser. it should be simple. it's not.
most agent tools open a fresh browser or a separate profile. want to reuse your own? they copy your profile into the agent's, slow, and half the time your logins break.
chrome 146 shipped CDP remote debugging (chrome://inspect/#remote-debugging). in theory, this lets an agent control your real window. i tested it. flaky on anything longer than a few minutes. weird bugs, no consistency.
the move that works: a browser extension, like what manus does. install the playwright extension, connect it via playwright cli or mcp, and the agent drives your current window directly. same cookies, same logins, nothing new to launch.
tested it through a long coding practice grind. didn't drop once.chromewebstore.google.com/detail/playwright-extension
