Greetings, about week or more ago whenever I would open Firefox two instances would pop up and to fully close Firefox I would have to exit out of both. While it is a rather small inconvenience having to swipe twice to fully quit the app it's slowly becoming more annoying especially when I am going through my open apps and two Firefox browsers get in the way of me finding the app I need or when I am trying to look at something from another open app quickly. Any help would be appreciated. I have a Pixel 3a running Android 11 and Firefox is updated to the most recent version. Also, I do not have any add-ons or pluggins. I have included a screen shot of what it looks like Thank you!
