The "Block Site" browser extension is a useful tool for blocking specific websites or domains to help you maintain focus and productivity while browsing. Here's how it works: Blocking Websites: To block a website or domain, right-click on any webpage and select the "Block this website" option from the context menu. This will add the domain address to your block list. Block List: The blocked domains are listed in the extension's options page. You can access the options page to manage your block list, including adding new domains or removing existing ones. Redirect Option: For each blocked domain, you have the option to set a redirect URL. Instead of blocking the website, it will be redirected to the specified URL. This can be useful if you want to replace distracting websites with more productive ones. Block Iframes: The extension also allows you to block specific iframes. You can add iframe URLs in the designated area on the options page. Reporting Bugs: If you encounter any issues or want to report bugs, you can visit the extension's homepage and fill out the bug report form. "Block Site" is a helpful tool for maintaining focus and controlling your browsing habits by blocking specific websites or redirecting them to more productive resources.
