Frequently Asked Questions

  • 1. What is Host Blocker?

    Host Blocker is a lite multi-browser addon that lets you easily block unwanted domains (hostnames). It has 19 predefined filter lists to choose from. Each list has several rules in it, once you select multiple lists the addon will merge them to construct a single list with unique rules. Once you add this addon to your browser, a button will appear in the toolbar. This button shows that the addon is active (with a red color). Now, before using the addon, please visit the options page and choose desired filter list(s). By default, three lists are selected. Please note that, you can choose to print blocked URLs to the browser console. To do so, please mark the first setting in the options page. If you want to exclude a website from blocking, please add its domain in the designated area within the options page. By default, there are some websites added, but you can edit this list at any time.

  • 2. How can I disable the addon?

    In order to disable the addon, please click on the toolbar icon once. When the color turns to gray, the addon is disabled. Alternatively, you can open the extensions tab in your browser and disable the addon from there. Please note that, once you disable the addon, you need to refresh all open tabs to unblock previously blocked URLs.

  • 3. How can I download the source code for Host Blocker - Block By Domain?

    To download the source code for this extension from Chrome Web Store, it is recommended to use Extension Source Downloader. With this addon, you can download the source code as a ZIP or CRX format to your machine. If you want to download the source code from the Firefox addons store, please open the firefox download link (if available) in the Firefox browser and then right-click on the - Add to Firefox - button and select - Save Link As... - item. Choose the destination folder on your machine and then save the file in XPI format. You can then rename the XPI format to a RAR or ZIP file. Some extensions may have a GitHub repo address, which you can use to download the source code as well. But, it may not be the latest version of the addon. Therefore, downloading the source code from the official web stores is the best option as it always gives you the latest version of the addon.

  • 4. How many blocking lists can I select?

    You can select as many lists as you want, but please keep in mind that, selecting a lot of filtering lists may affect your browsing experience, but this depend on your system speed as well. In the options page, when you select a blocking list, it shows the number of unique rules in it (at the end on the line for settings 2), when you add two or more lists, the number of unique rules will increase. Once the filtering list is constructed, the addon needs to check each URL against all these rules to determine which domain is unwanted. Therefore, when the list is too long, this process will take more time and might affect your browsing experience.

  • 5. How can I add a domain to the whitelist?

    As mentioned above, in order to add a domain to the whitelist, please write the domain name in section 3 within the options page. Please add domains comma separated, for example, oo1.com, foo2.com, foo3.com, etc. When you add a domain in whitelist section, the addon will not monitor that specific domain (and all subdomains). Some domains are added to the list by default, but you can edit this list at any time.

    Yes, but when you first add this addon to your browser, please visit the options page to adjust blocking lists. By default, 3 items are selected. Once you select an item(s) from the options page, please reload all open tabs for the addon to take action.

  • 9. How do I unblock a URL (not domain)?

    This addon works based on domain or hostnames. In other words, it only looks at domains or hostnames for any URL. So the whitelisting function only works based on domain matching. Currently, there is no way to whitelist a URL alone, and the whole domain will be whitelisted instead.
