Mini Firefox icon on end of dock in macOS Big Sur 11.2.3
Long story short... this is my first Mac (MacBook Pro 13-inch, M1, 2020). I noticed that there is a mini Firefox icon at the end of my dock before the "stack" downloads folder and trash icon. I was wondering if anyone else has the same issue. Restarting seems to help but comes back, removing Firefox from the dock also seems to help but once it's back in there it comes back after a while.
