Block a Website in Firefox on Mobile

The process for blocking a site in Firefox is a bit different on your iPhone, iPad, or Android device. Android provides a little more flexibility than iOS and iPadOS. You can download a free add-on for Android called Leechblock NG. It has mostly positive ratings, and it’s Firefox-specific, meaning it won’t restrict sites in other browsers, like Google Chrome.

After you install Leechblock NG, you just add the sites you want to block to the block list.

If you want to block a site on your iPhone or iPad, however, you have to do so via Screen Time. Any site you add to that list isn’t just blocked in Firefox; it’s blocked in any browser on any device that uses your iCloud account.

To set it up, go to Settings > Screen Time > Content and Privacy Restrictions. Toggle-On the “Content and Privacy Restrictions” option, and then tap “Content Restrictions.”

    How to block a website in mozilla firefox

    There are many reasons why you might want to block a website from your computer. The website might contain a virus that can infect your whole computer and jeopardize all of your files. Others could just be annoying pop-ups and some could contain explicit content that you don’t want to see or that that you don’t want your children to see. If you are a Mozilla Firefox user, blocking websites from the browser is quite easy. We’ll tell you just how easy it is in this OneHowTo article, how to block websites in Mozilla Firefox.

    The easiest way of blocking websites in Mozilla Firefox is by using a free add-on called BlockSite. The BlockSite extension blocks sites which are added to its ‘black list’, but it can also be configured to disable links to blocked sites so that they don’t work rather than showing their hyperlinks. BlockSite also has ‘password protection’ that helps prevent unwanted changes to BlockSite. To get BlockSite working, go through the following simple steps.

    How to block a website in mozilla firefox

    For the first step, open Firefox, click ‘Tools’ and then ‘Accessories’. Click ‘Get add-ons’ and then ‘Browse all add-ons.’ Type ‘BlockSite’ in the search bar after Mozilla Firefox opens and hit ‘Enter.’

    Next, click the ‘Add to Firefox’ button next to BlockSite. Allow the add-on to load (usually less than 5 seconds), then click on ‘Install Now’. Restart Firefox when you are prompted.

    Go to ‘Tools’ then ‘Accessories’ then click the BlockSite ‘Preferences’ button after restarting Firefox. Make sure the radio button ‘blacklist’ is checked and ‘Enable BlockSite,’ ‘Enable warning messages’ and ‘Enable link removal.’

    Type ‘Allow authentication’, then type a password if you want to prevent users from other blocked websites deleting or changing the settings in BlockSite without your permission.

    Finally, click the ‘Add’ button, enter the URL of the website you want to block then click ‘OK’. To add more sites, repeat this process, or to clear the list, click the ‘Clear’ button. Once the list of blocked sites is complete, click ‘OK’ and restart Firefox.

    How easy was that!? Now you will be able to browse with Mozilla Firefox and be free from any unwanted websites.

    When I try to click on a link to www.bookbub.com/ in Google Reader and feedly, I get the following message: “Firefox prevented this site from opening 1 popup window”, with an option box to either:

    option 1 – “Block popups from google.com” (or feedly.com) – I want the opposite of this!

    option 2 – “Edit popup blocker options”

    If I click on option 3 (“Show www.bookbub.com/deals”), this website is still being blocked.

    If I choose option 2 (allow popups from google and feedly), this website is still being blocked.

    So, in Firefox Options settings, the popup blocker box is now unticked – popups are unblocked – but this website is still being blocked.

    This is the only site which is blocked. All links to other websites open correctly from Google Reader and/or Google Search. To bypass this unwanted block and access the website, I have to type the url in the address bar.

    I would much prefer to simply open it as I do with all other websites from Google reader or feedly, with a simple click on a link.

    Suggestions welcome, thank you.

    Same problem when clicking on a link to this website from Google Search (website blocked by Firefox), yet no such problem when clicking the link within *this* post. ?!

    No problem whatsoever opening the website from any link in Chrome.

    Thanks for the suggestion.

    You can easily block websites on Firefox — but you’ll need to download an extension first.

    Then, you can access your settings and add blocked websites to the “Add-ons” section of your Firefox Settings menu.

    Along with adding a site to the list, you can also add a password to unlock blocked sites or have blocked sites instead redirect to a different website.

    You can also delete sites from the list at any time.

    Here’s how to do block sites on Firefox.

    How to download the Block Site desktop extension for Firefox

    Before using the Block Site extension, you’ll have to download it to your PC or Mac computer. You can easily find the extension by searching for it on Google or by heading to the main Mozilla site.

    1. Click the blue “Add to Firefox” button.

    2. This will open a pop-up confirming the decision. Click “Add.” This grants the extension permission to access your data, browser tabs, and display any notifications.

    3. Firefox will automatically add the extension to your browser. A separate pop-up will appear confirming that it has been added, along with instructions on how to manage your add-ons.

    How to block a website on Firefox using the Block Site extension

    1. Click the three bars in the top-right corner of your screen.

    2. Click “Add-ons.”

    • You can also hold the “shift” + “command” + “A” keys on your Mac keyboard, or “SHIFT” + “CTRL” + “A” on your PC, to access this menu.

    3. This will bring you to a settings page. Click “Extensions” on the left hand side, and you’ll find a list of enabled add-ons under the “Manage Your Extensions” section. Click on “Block Site.”

    4. On the next page, click the three dots.

    5. Click “Preferences.”

    6. This will open an options page for Block Site in a new tab. Though there are lots of options, you really only need to focus on a few sections. It’s not necessary to do, but you can also follow the prompts provided to change settings like the user message, how long before a blocked tab closes, or time and day limitations for blocked sites.

    7. You can add a master password at the top, so you can view a blocked site if needed.

    8. You can also add a site under “Redirect to.” For example, a blocked site will always redirect to Google or the Firefox homepage.

    9. After you’ve made any changes, enter the site’s URL in the “Block a new hostname” space.

    10. Click “Add.”

    The blocked site should appear under the “Matching Pattern” section. You also have the option to add a “Redirect to” site here.

    You can remove a site at any time in this section as well.

    Now, when you try to access that site, you will receive a blocked message. Enter the master password, if you set one, to temporarily unblock the site, if needed.

    How to block a website in mozilla firefox

    Every time I search anything, I always get nude women, men, sexual content. Doesn’t matter what words I type in, pornographic content is included in the images window. How do I stop this from happening?

    Chosen solution

    There are several ways you can do this:

    1. Speak to your Internet Service Provider (ISP). Many have filtering and parental controls they can put in place to reduce the chances of seeing that type of material.
    2. You may wish to use a Firefox Add-on. A list of some that may help can be found here.
    3. There may be controls included with the operating system of the device that you are using. I recommend consulting a specialist Apple forum for help with this.

    I hope this helps, but if not, please come back here and we can look into a different solution for you.

    Whichever search tool you are using should have a setting that will help with this. Google, for example, under Settings has a Safe Search setting.

    “SafeSearch Filters SafeSearch can help you block inappropriate or explicit images from your Google Search results. The SafeSearch filter isn’t 100% accurate, but it helps you avoid most violent and adult content.”

    There is a box to turn this on and another to lock it on.
