Privacy Hive understands the importance of protecting your online privacy. One way to do this is by using a privacy-focused browser. Additionally, you can further enhance your online privacy by installing browser extensions, which are small software programs that can be installed on your web browser.
In this blog, Privacy Hive will focus on four types of Firefox browser extensions that can help protect your online privacy: (1) ad and tracker blocking, (2) fingerprint protection, (3) user agent string protection, and (4) containerization.
(1) Ad and tracker blocking: Advertisements and trackers can be used to collect data about your online behavior. Browser add-ons such as Ublock Origin can block ads and trackers by blacklists, which are a list of unsafe URLs, IP addresses, or domain names that are removed from the search results by authorities such as search engines like Google and Bing or antivirus service providers like McAfee, SiteAdvisor, and Norton, Safe Web.
Additionally, blacklists are used to protect users from malicious websites that may contain malware or phishing scams. Websites that are on a blacklist are removed from search results and are flagged as unsafe. It is important to note that blacklists are not foolproof and that it is still essential to be cautious about the websites you visit and the information you share online.
(2) Fingerprinting protection: Websites can use browser fingerprinting to track your online behavior. Browser fingerprinting is a technique used to track users online by collecting and analyzing various unique characteristics of a web browser to create a distinctive identifier or “fingerprint” for that browser. These characteristics include, but are not limited to, the following:
- Browser type and version
- Operating system
- Installed plugins
- Time zone
- Language
- Screen resolution
- Hardware details
Combining enough of these characteristics makes building a unique fingerprint on a user’s device possible. This technique is stealthy and difficult to block, making it a popular choice for tracking companies.
Browser add-ons such as Canvas Blocker can protect you from fingerprinting by blocking websites’ scripts to collect your fingerprint data.
(3) User agent string protection: A User-Agent (UA) string is an alphanumeric string identifying the ‘agent’ or program requesting a web server for a digital asset such as a document, image, or web page. The User-Agent string is handy because it gives you information about the software and hardware running on the device making the request, like the operating system and browser versions. Websites can use your browser’s user agent string to track online behavior. Browser add-ons such as User-Agent Switcher and Manager can protect you from user agent string tracking by allowing you to spoof your browser’s user agent string to a custom designation, making it impossible for websites to know specific details about your browsing arrangement.
(4) Containerization: Browser containers are a privacy feature that helps you protect your online identity. They allow you to separate your browsing activities into different color-coded tabs for work, banking, shopping, and personal browsing. Using these containers, you can categorize your browsing based on purpose and create tabs for each category. This helps to prevent websites from tracking your online activity and collecting data about you.
Firefox Multi-Account Containers is an extension developed by Mozilla that allows you to use containers to protect your privacy. You can sign into multiple accounts on a single website, prevent tracking and security attacks, assign websites to containers, and hide/show and sort tabs.
In conclusion, browser add-ons can provide additional online privacy protection beyond what a privacy-focused browser can offer. Ad and tracker blocking, fingerprint protection, user agent string protection, and containerization are four types of browser add-ons that can help protect your online privacy and protect you from malicious websites and online tracking.
