Prevent PyCharm from launching in browser / new tab

I found several people who want PyCharm to open a browser / new tab every time you hit the start button.

• https://intellij-support.jetbrains.com/hc/en-us/community/posts/206590705-How-do-I-setup-Run-Debug-Config-to-open-browser-automatically-for-Flask-
• Django manage.py runningerver doesn't open browser

Okay, I click frequently run

and already open the tabs that I need. Quite difficult to close new ones and I want to disable it. I have looked through all the menus and I cannot find the setting Run browser

that some people are talking about.

I also tried to disable all Django support for browsers in Settings -> Tools -> Browsers, but that didn't matter.

Versions:

• PyCharm 2017.1.1
• Python 3.5.x
• Django 1.10
