How to Block or Allow Browser Cookies in Firefox Computer

Cookies are introduced to make your browsing experience more comfortable by remembering website paths and login credentials. However, there are some times when you need to disable it to stop privacy invasion from different sources.

You can even disable or enable Firefox browser cookies as per your preferences. But remember that blocking Firefox cookies will impact your browser’s functioning. You won’t be able to benefit from auto-sign and other essential browser features.

Mozilla Firefox offers multiple settings to protect privacy; hence blocking/allowing cookies is relatively easy. It has several options to block cookies or perhaps allow only specific sites.

Block/Allow All Cookies

There are several sites you visit every day that relies on cookies to enhance your browsing experience. They are not a severe threat to your security and privacy as most people tend to think. But if you find anything very absurd, blocking cookies should be your priority. Follow these steps to disable/allow cookies:

1. Launch Mozilla Firefox on the computer.
2. Click on More for the menu list.
3. Select the Settings tab from the list.
4. Switch to the Privacy & Security tab from the left side pane.
   You will now see Enhanced Tracking Protection with three options: Standard, Strict, and Custom.
   
5. Choose the Custom settings to expand.
6. Enable the checkbox for Cookies.
   
7. From the drop-down, select All cookies if you want to block all cookies.

That’s it. All the browser cookies will be blocked and no longer saved on the Firefox browser. You should avoid blocking All cookies since it will break the site’s functioning.

Perhaps, you should prefer blocking Cross-site and social media trackers only. This will make most sites work without any issues. Even blocking All third-party cookies on Firefox might lead the site to break.

Allow/Block Cookies for a Site

You can block cookies for a single website just like blocking all website cookies. If you think a particular site should not have any of your data, then blocking the cookies should be your preference. Here are the steps to stop/enable cookies for specific websites:

1. Launch the Firefox browser on your computer.
2. Open and visit the website where you want to block cookies.
3. Right-click on the webpage and choose View page info. 
   This will open the Page Info window.
4. Switch to the Permissions tab within the window. 
5. Locate the Set Cookies option and uncheck the Use default option.
6. Select the Block/Allow radio button for Set Cookies.
   

It will disable/enable the browser cookies for your intended website. Next time you visit the same website, the cookies won’t be stored on the website if you’ve blocked them.

Allow/Block Multiple Site Cookies Easily

The above method is quite cumbersome if you want to block a few websites. You need to try the above steps for each website. Instead, you can use the Manage Data option within Firefox to block or allow specific sites in one go.

Here are the steps to allow/block cookies for multiple sites:

1. Launch the Firefox app browser.
2. Click on More to open the menu list.
3. Select the Settings menu from the list.
4. Switch to Privacy & Security tab from the left pane.
5. Scroll down to find the Cookies and Site Data section.
6. Hit on the Manage Data… option.
   
   This will open the cookies and site data pop-up window.
7. Enter the Site URL of the website in the Address of website field.
8. Click on the Block or Allow button per need.
   
9. Hit the Save Changes command button.

Repeat steps #7 and #8 until you add all the website URLs in the Manage Data window. It will disable or allow the cookies for all the websites you have entered in the given area.

Bottom Line

We can’t deny that browser cookies are vital in improving your browsing experience. They help you skip entering your login information by remembering them.
