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.

Yesterday, my sister consulted me with a similar issue. She wanted to disable her browser cookies as they were causing her system to lag. I decided to help her in blocking the browser cookies on the Firefox browser.

Even you can simply 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 take benefit of auto-sign and some other essential browser features.

Mozilla Firefox offers multiple settings to protect privacy, hence blocking/allowing the cookies is quite easy. It has quite a few options where you can block cookies or perhaps allow only specific sites.

Block/Allow All Cookies in Firefox

There are several sites you visit every day that relies on cookies to enhance your browsing experience. They are not a serious threat to your security and privacy as most people tend to think. But, if you found anything very absurd, then blocking cookies should be your priority.

Follow these steps to disable/allow cookies on your Firefox browser: 

1. Launch Mozilla Firefox on the computer.
2. Click on the menu list.
3. Select the Settings to tab from the list.
4. Switch to the Privacy & Security tab from the left side pane.

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 in Firefox

Just like blocking all website cookies, you can also block cookies for a single website. If you think a particular site should not have any of your personal data, then blocking the cookies should be your preference.

Here are the steps to stop/enable cookies for specific websites on Firefox: 

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 the website that you intended for. Next time when you visit the same website, the cookies won’t be stored from the website if you’ve blocked them.

Allow/Block Multiple Site Cookies Easily

Now, 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 on firefox:
