My problem is similar to https://intellij-support.jetbrains.com/hc/en-us/community/posts/115000097590-JetBrains-Chrome-Extensions-with-Multiple-JetBrains-IDEs-WebStorm-PyCharm-?input_string=Jetbrains%20IDE%20Support%20chrome%20addon
but rather than mutliple IDE's I have multiple project windows. When I click the IDE support addon a debugging session starts but in the wrong project. I have to close all other project windows until only the one I want is left. I don't know if I'm unlucky but it always seems to be the last window open that is the one I want!!
How do I bind the button to a specific project? The button is so good because because you can start an adhoc debug session as easy as an in browser session. The debug profile route is too long winded.
