Mozilla Introduces Total Cookie Protection to Firefox

Mozilla has added a Total Cookie Protection feature to Firefox‘s Strict Enhanced Tracking Protection (ETP).

There’s no denying that cookies are a useful technology.

Thanks to those little morsels, web developers can provide a more personal and convenient website visit. They let websites remember you — your logins and shopping carts, among others.

Unfortunately, cookies also pose a serious privacy issue.

That’s because web browsers allow cookies to be shared between websites. As a result, trackers can quickly tag and follow you from one website to another.

Indeed, this type of cookie-based browsing may be the most prevalent method of collecting user data.

Unsurprisingly, several browsers introduced new features to limit cookie tracking. In 2019, Mozilla added Enhanced Tracking Protection to Firefox to block trackers.

For example, it blocked cookies such as:

  • Cross-site cookies
  • Cryptominers
  • Social media trackers
  • Fingerprinter
  • Tracking of content in private windows

Now, the company is taking its fight to protect web users’ privacy to the next level. Last Tuesday, Mozilla has announced the new Firefox 86 and its Total Cookie Protection.

Here’s how it works.

Using the Total Cookie Protection in Firefox 86

According to Mozilla, Total Cookie Protection works by maintaining a separate “cookie jar” for each website you visit.

So, when a website deposits a cookie in your browser, it is automatically confined to its specific cookie jar. That way, it becomes impossible to share the cookie with other websites.

With that said, Total Cookie Protection makes a limited exception for some unique types of cross-site cookies.

According to executives at Mozilla:

“Total Cookie Protection makes a limited exception for cross-site cookies when they are needed for non-tracking purposes, such as those used by popular third-party login providers.”

To activate Total Cookie Protection, navigate to a webpage on the Firefox 86 browser. Then, click the shield on the left side of the address bar.

The Firefox Preferences Privacy & Security panel should pop up when you select the Protection Settings. From there, toggle Enhanced Tracking Protection on.

Finally, reload all the open tabs to activate the new privacy feature.

    One has to be careful with the brokers on the internet now. Last year I was scammed in the binary trade option by a broker I met on Instagram. I invested $14000 which I lost, I couldn’t make a withdrawal and I slowly lost access to my trade account for 3 months I was frustrated and depressed. After a few months, I met Mrs Lisa who is A recovery expert that works in affiliation with the Federal Bureau of Investigation (FBI) and other law firm. she worked me through the process of getting my money back and all the extra bonus which I got during my trading. he can be of help to anyone who has a similar situation. You can contact him via her mail: Email Lisa.Eric @ WhatsApp +84 94 767 1524

    In the world of cryptocurrency trading and investing, you need to be careful about the risks involved. I was naive enough to believe that I could make huge profits without doing proper research on the subject. I lost $243,000 in USDT and BTC due to a failed cryptocurrency investment plan. Fortunately for me, I was able to contact a reputable cryptocurrency recovery company known as Alien Coin Recovery. I was skeptical at first, but their professionalism and proven experience reassured me. The recovery process involved providing detailed information about the fraud, including transaction history and communication records. I managed to get back all the money I invested in the fraudulent investment scheme. I am grateful to Alien Coin Recovery for their honesty. Here is a recommendation for everyone who intends to recover lost funds. Alien Coin Recovery is the most reliable team.
