How to protect your privacy in popular web browsers: Google Chrome, Mozilla Firefox, and Safari
Paranoia is good in moderation.
In the Incognito mode, Chrome doesn’t remember the pages you visit or the searches you submit. The data that you occasionally enter into forms is not recorded either. However, the only real perk of Chrome is that it doesn’t save your site visit activity. Other sources, such as your internet service provider, like AT&T, your school IT guy, system administrators, your employer, and the websites you visit can track you down and snoop in on your network activity.
Enable Firefox’s Private Browsing or Chrome’s Incognito Mode, despite its imperfections.
Remember, everything has its pros and cons. The private mode makes your browser to ignore cookies, neither it records the browser’s history. This type of security is good enough for hiding from your brother who uses your computer. But ad trackers and ISPs are still capable of sniffing your records. On Mac, press ⌘ + Shift + N. It will bring up the Incognito mode.

Add Ghostery’s extension to your browser.
When you visit a site, Ghostery collects the data about the site, its trackers, and identifies what’s going on. It’s important to know that Ghostery only scans “http” and “https” pages. You can fill out the “trusted sites” chart to unblock safe websites.

Install AdBlock Plus to disable the ads.
As you can see, I already have it added to Chrome. You can enable the option of supporting a specific site through ads. Usually, it asks for permission to do so. Or instructions how to whitelist a specific website.

Disable JavaScript manually on the individual untrusted websites.
YesScript add-on works for Firefox. In Chrome, you can can disable it manually for each website.

Activate the “Do Not Track” option in the browser.
Disable third party cookies.

You can disable the search history in Chrome to “read only.”
Prevent Chrome from writing its history file.
Try out Duckduckgo. It’s a convenient search engine that doesn’t track you. It has an encrypted Google shortcut too. Prefix your search with “!g.”
Their privacy policy is simple. They don’t collect or share any of our personal information, store search history, don’t sell our information to advertisers, or track us during private browsing mode.
