Block Site (formerly known as Stop Social Media) is a simple Chrome extension that improves your productivity by blocking access to distracting websites as you specify.
To configure, click on the B icon in the toolbar and select Options from the menu. Enter sites in the textbox, leaving a new line for each site, like this:
facebook.com
instagram.com
youtube.com
!music.youtube.com
twitter.com
reddit.com
!reddit.com/r/MachineLearning
Sites starting with ! will be exception to the rule, allowed.
Choose what should be done when you try to visit a blocked site, options are:
- Close Tab
- Show Blocked info page (page that shows an information about the blocked site)
Last but not least, see a checkbox to enable/disable the blocking.
