Distraction Block by Lyndi Castrejon

Create a custom block list for any web address you would like to block. Easily enable/disable the Add-on with one click.

Why does Distraction Block need permission to "Access your data for all websites"?
This permission is REQUIRED for the extension to detect when you visit a blocked site. Without it, the extension cannot intercept navigation to blocked websites and display the block page. Distraction Block only checks the URL of pages you visit against your personalized block list and does not collect, store, or transmit any browsing data.

Privacy
Distraction Block operates entirely on your device. Your blocked site list is stored locally on your computer and is never sent to external servers. The extension does not track your browsing history or collect any personal data.
