If you want to control access to websites on just one machine, then you can set up block at the operating system level. This method for blocking websites is not too hard to configure and will work across browsers.
Windows
One of the backbones of the Internet is the DNS system that translates easy to remember (and type) names such as www.google.com into equivalent IP addresses (8.8.8.8). While you use DNS servers to get to websites, your computer also has something called a HOSTS file which can have this information stored locally. This can be used to disable access to unwanted websites. We checked this method with both Windows 7 and Windows 8.
1. Make sure you have administrator access on your computer. Sign in to your PC using an administrator account and go to C:\Windows\System32\drivers\etc\
2. Double-click the file named "hosts" and select Notepad from the list of programs to open the file. Click OK. The last two lines of your hosts file should read "# 127.0.0.1 localhost" and "# ::1 localhost".
2a. In case you can't edit the file, you'll need to right-click the file labelled hosts and select Properties. Click the Security tab, select the administrator account and click Edit.
2b. In the pop-up, select the account again and check Full control. Click Apply > Yes. Now click OK in all pop-ups.
3. At the end of the file, you can add the addresses of websites to block. To do this, just add a line at the end of the file, with 127.0.0.1 and then the name of the site you want to block - this will redirect the site's name to your local computer.
4. To block Google, for example, add "127.0.0.1 www.google.com" to the end of the file without the quote marks. You can block as many sites as you want this way, but remember you can only add one per line.
5. Repeat this step until you've added all websites you want to block.
6. Now close the hosts file and click Save. Reboot your computer for the changes to take effect and you'll find that all those websites are now blocked.

Here's how to block websites on OS X .
1. Make sure you have administrator access to your Mac. Now open Terminal. You can find it under /Applications/Utilities/Terminal.
2. Type sudo nano /etc/hosts and press enter. Enter the user (login) password when prompted.
3. This will open the file /etc/hosts in a text editor. Type the name of the website in a new line in this format "127.0.0.1 www.blockedwebsite.com" (minus the quotes). For each website you want to block, start a new line and type the same command with only the name of the website being replaced. When done, press ctrl+x and then Y to save changes.
4. Now key in the command sudo dscacheutil -flushcache and press Enter or restart your machine to make sure the websites are blocked.
Browser-level blocks
Blocking a website on any browser is the easiest way to get the job done.
On Firefox, you can install an addon called BlockSite to block website.
1. Install the addon, press ctrl+shift+a, and click Extensions on the left. Now click Options under BlockSite. In the pop-up, click Add and type the name of the website you want blocked. Repeat the process for all websites you don't want to access. Click OK.
2. Now these websites will be blocked on Firefox. You can also set a password in BlockSite to prevent others from editing the list of blocked websites. This can be done via the options menu described in the previous step.
BlockSite is also available on Google Chrome.
Internet Explorer lets you block websites easily. Here's how.
1. Open the browser and go to Tools (alt+x) > Internet Options. Now click the security tab and then click the red Restricted sites icon. Click the Sites button below the icon.
2. Now in the pop-up, manually type the websites you want to block one-by-one. Click Add after typing the name of each site. When done, click Close and click OK in all other windows. Now these websites will be blocked in Internet Explorer.
On your phone or tablet
iOS
Apple has some handy parental control tools that let you block certain websites. Here's how.
1. Go to Settings > General > Restrictions.
2. Tap on Enable Restrictions. Now set a passcode for restrictions. This should ideally be different from the passcode you use to unlock the phone.
3. After the passcode is set, scroll down and tap Websites. Here you can either choose to limit adult content, or allow access to specific websites only.
4. In specific websites only, there's a short list of allowed websites including Discovery Kids and Disney, but you can also add sites by tapping on Add a Website.
5. If you tap Limit adult content, Apple blocks websites that are deemed objectionable, but you can whitelist websites by tapping on Add a Website under Always Allow, or blacklist them by tapping on it under Never Allow.
6. If you try to access a blocked website, you see a message telling you it is restricted. Tap the Allow Website and key in the Restrictions passcode to open that website.
Android
On Android, you'll need to edit the hosts file on your device to redirect sites you want to block. You'll need a file manager, and a text editor - the easiest option is to use our favourite app ES File Explorer, which lets you do both things. Here's how it works.
1. Install ES File Explorer Open ES File Explorer and tap the "/" button at the top. Tap on system > etc.
2. In this folder, you'll see the hosts file - tap it and in the pop up menu, tap text. In the next pop up, tap ES Note Editor.
3. Tap the three dots button in the top right, and tap edit.
4. Now, you're editing the file, and to block sites, you want to redirect their DNS. To do this, just start a new line, and type "127.0.0.1 www.blockedwebsite.com" (without the quotes, where blocked website is the name of the site you're blocking) for each website you want to block. For example, you'll have to type 127.0.0.1 www.google.com to block Google.
5. Reboot your Android device.
If that method is too complex for you, you can install an anti-virus app such as Trend Micro that lets you block websites.
1. Install the app and run it. Go to Options > Safe surfing.
2. Now swipe to Parental Controls and click set up account. Create an account and you'll see an option called Blocked List in the app. Tap it, and tap Add. Now add the websites you want to block one at a time. Once that is done, you won't be able to access these websites on your Android smartphone.
Windows Phone
You can't do a full block of websites on Windows Phone, buy you can download the AVG Family Safety browser. By default it blocks websites with malicious or explicit content, and if you purchase an AVG anti-virus licence and create an account, you can customise the list of blocked websites.
