For computer workers, they will definitely hope to be able to focus at all times during working hours, maintain a high level of concentration, and not be distracted by other things, but this is a very rare thing, especially when you open the Chrome browser and prepare to find information, you will unknowingly look at Facebook, Instagram, etc., and then waste 30 minutes or even an hour. And this Stay Focused free extension plug-in can help you. After turning on the focus mode, the set websites will be blocked, making it impossible to browse normally. Even canceling focus is a little troublesome, giving you more time to think.

Then when you enter a website on the blocked list, you will automatically jump to a screen asking you to stay focused, and it will also be paired with some interesting GIF files, like the picture below of the most popular professional team of black coffin bearers:

The GIF file you open is different every time, which is very interesting:
