Allows a maximum of 3 open tabs
Work with more focus. If you open a fourth tab, the extension automatically closes the fourth tab and notifies you with a pop-up (just press Enter to close the pop-up). Forces you to finish tasks before starting new ones.
I've used this extension for years, and I love it! It's in my browser right now. If you use this extension frequently, please leave a 5-star review.
