Q600: Where can I find Tampermonkey's console output?

A600 Before getting the output you have to enable debug output. Just click at the Tampermonkey icon, choose "Dashboard", select the "Settings" tab and set "Logging Level" to "Debug"". ( video tutorial)

There are 3 different consoles that Tampermonkey might write log messages to.

  2. Find Tampermonkey and click Details.
