Are you concerned about how cookies may be compromising your privacy? Unsure how to manage cookie settings on Firefox across all your devices? If so, you‘ve come to the right place.
In this comprehensive guide, I‘ll explain everything you need to know about disabling cookies in Firefox – with detailed instructions for Windows, Mac, Android, and iOS.
By the end, you‘ll understand the risks cookies pose and be able to configure Firefox‘s powerful controls to protect your data. Let‘s dive in!
What Are Cookies and Why Are They a Privacy Risk?
First, what exactly are cookies and how do they threaten your privacy?
Cookies are small text files that websites place on your device to identify your browser or mobile app on return visits. They can serve legitimate purposes like remembering usernames or tracking your progress through a multi-step process.
However, the vast majority of cookies today are used to monitor you across multiple sites and build detailed profiles about your interests, habits, and more. They empower companies to target ads and content to your specific tastes – all without your informed consent.
For example, say you visit CNN.com which has embedded Facebook buttons. Facebook drops a cookie which then tracks you as you visit NYTimes.com, ESPN.com, weather sites, or anywhere else across the web.
This allows Facebook to assemble an intimate portrait of your browsing activity and personal interests to serve hyper-targeted ads. Other third-party trackers like Google and data brokers also leverage cookies in similar ways.
This kind of covert surveillance understandably raises privacy concerns. In fact, a 2021 Pew Research study found that 81% of Americans feel they have no control over the data collected about them online. The same study reported 64% have decided not to use a product or service due to privacy concerns.
And the risks go beyond just personalized ads. A Princeton study found cookies can be used to infer highly sensitive information about users like religious beliefs, sexual orientation, or health conditions based on their web activity.
Fortunately, tools like Firefox give you control to limit these risks. Which brings us to…
Step-by-Step Instructions to Block Cookies in Firefox
Firefox offers robust controls to block invasive tracking cookies and protect your privacy. Here are detailed steps for disabling third-party cookies:
On Windows and Mac:
- Click the menu button in the top right and select Preferences
- Go to the Privacy & Security tab
- Under Enhanced Tracking Protection, choose Custom
- Check Cookies and select All third-party cookies from the dropdown
- Click Reload All Tabs so the changes take effect immediately
That‘s all it takes to disable third-party cookies! This will prevent sites like Facebook from snooping on your activity across the web.
On Android devices:
- Open the Firefox app and tap the menu button (3 horizontal lines)
- Select Settings then scroll down to Privacy and Security
- Tap Block Cookies and choose which ones you want to disable
On iPhones:
- Open Firefox and navigate to the site where you want to block cookies
- Tap the shield icon next to the URL bar
- Toggle Enhanced Tracking Protection on and select cookie types to block
- Tap Done to save changes
So in just a few taps, you can be blocking invasive cookies on mobile too!
Enabling Cookies on Specific Sites
You may notice some websites break when you block cookies. Images and videos may not load or you can‘t log in, for example. Don‘t worry! You can still allow cookies on a site-by-site basis:
- Visit the site where you want to permit cookies
- Click/tap the shield icon next to the address bar
- Toggle the Enhanced Tracking Protection switch OFF
- Reload the page and third-party cookies will be active for this site
I recommend keeping cookie blocking on as the default, and just making exceptions for sites you trust or need cookies enabled for full functionality. This balances privacy and user experience.
Complement Firefox‘s Protection with Ad Blockers & VPNs
To take your online privacy to the next level, pair Firefox with additional tools like:
- Ad blockers – Block ads and stop more trackers from monitoring your web activity. I recommend uBlock Origin.
- VPN – Encrypts all traffic so your browsing history can‘t be tracked. Many leading VPNs like ExpressVPN also block ads, malware, and trackers.
Combining these with Firefox‘s baked-in protections offers multilayer privacy for peace of mind.
Firefox Cookie Myths – Debunked!
There are a lot of misconceptions around Firefox‘s cookie handling. Here I‘ll address some common myths:
Myth: Firefox doesn‘t block cookies at all!
Fact: Not true! Firefox blocks cross-site/third-party tracking cookies by default to prevent covert monitoring.
Myth: Disabling cookies deletes all my saved passwords.
Fact: Passwords are stored separately by Firefox‘s password manager so they are retained even if you delete cookies.
Myth: Firefox doesn‘t auto-delete cookies.
Fact: You can configure Firefox to clear cookies on exit or at set intervals for convenience.
Myth: All cookies are bad for privacy.
Fact: First-party session cookies can offer useful functionality without tracking. Firefox gives you granular control over cookie types.
