Dash keeps opening new browser tabs with a new application instance, why?

For some reason, my app keeps opening new browser tabs without me making any changes to the code. Did anyone else experience this? I am running in WSL2 (Windows subsystem for Linux).

I would appreciate any hints on how to troubleshoot this. I never experienced this before.

That happens in debug mode and also when serving the app with waitress.
It is pretty distracting.

I’m having the same issue. I have a line in my init function to start the app in my browser, which should only open one instance of the app. It will remain stable for a bit, but when I click to another browser tab, it will start rapidly opening new tabs with my plotly dash app. It’s intermittent and very disruptive.

Here is a code snippet:

class dashboard(Dash):
    """ Class Wrapper for main GUI """
    def __init__(self,*args, **kwargs):
        Dash.__init__(self, *args, **kwargs)
        #%% APP SETUP
        host = socket.gethostbyname(socket.gethostname())
        self.layout = html.Div([

I’m running windows 10 64 bit OS, using Spyder 5.03 as my IDE and Firefox as my browser.
