About Block Site

*** Block Site is now on the safer manifest v3. Please report the compatibility bugs you are experiencing. You can export the current rules to a JSON file and send it to me to investigate. *** This extension will block access to websites of your choosing. A master password controls all customization options, as well as access to any blocked site. It's also possible to redirect navigation from one specific website to another. Features: 1. Block unwanted domains. 2. Prevent access to a range of websites using wildcard matching or regular expression matching. 3. Reverse mode allows access to only some hostnames and blocks access to all others. 4. Custom redirection; you can redirect a single blocked hostname to a new destination. 5. Display a custom message on blocked pages. 6. Time and date-based blocking. Only block access to the websites at specified times and dates. This feature can be configured per hostname. 7. Protect data leakage. This extension prevents certain hostnames from gathering network activity from your computer since blocking occurs before any network request is emitted to the server. 8. Auto-closes blocked tabs after some time. 10. Closes annoying pop-ups as soon as the opening request is received. 11. Pause and resume blocking from the right-click context menu of the toolbar button. 12. Support overwriting configurations by managed storage 13. Block cached page load with service worker 14. Block dynamic page change with history push method For the FAQs and general feature suggestions please use: https://webextension.org/listing/block-site.html For technical bug reports use: https://github.com/ray-lothian/Block-Site/issues
