I'm trying to launch a website URL in a new tab using python in that way, but it didn't work in these both ways:
Method 1:
os.system('C:\Program Files\Mozilla Firefox\Firefox.exe -new-tab http://www.google.com/');
and Method 2:
os.startfile('C:\Program Files\Mozilla Firefox\Firefox.exe -new-tab http://www.google.com/');
If I don't add the parameters (-new-tab http://www.google.com/) it works, opening the default page.
