Incognito is a good idea. You can even turn off autoplay permanently using it:
1. Log out from DirtyLeague in your normal browser session and close your browser.
2. Start an incognito browser and log in. Now you have an autoplayless session, enjoy it, play, then log out and close your incognito browser.
3. Next time you start your browser in normal mode and log in, you will have autoplay off.
Even though it is frustrating that we can't touch the auto button or it stucks in. Even more frustrating that I opened an error ticket about it two days ago, probably other users too, plus a few of us were complaining here in Feedback, and still no reaction. I hope Hooligart is still alive.
