Disabling javascript breakpoints usually does the trick. Devtools detection is often done by having a `debugger;` statement somewhere and timing of it triggered

A lot of them dynamically generate new anonymous functions to get around this. Last I looked (~1 year ago I think) neither Chrome nor Firefox supported disabling the keyword completely. Do you know if that's changed?

On Firefox its in the Debugger Tab of the DevTools. On the top right you can deactivate all breakpoints (which includes the debugger statement).

There is a similar button on chrome, but I am not sure if that also applies to the debugger statement.
