 **Block Ads** | Recommended | Using an ad-blocker can help improve your privacy, by blocking the trackers that ads implement. [uBlock Origin](https://github.com/gorhill/uBlock) is a very efficient and open source browser addon, developed by Raymond Hill. <br>When 3rd-party ads are displayed on a webpage, they have the ability to track you, gathering personal information about you and your habits, which can then be sold, or used to show you more targeted ads, and some ads are plain malicious or fake. Blocking ads also makes pages load faster, uses less data and provides a less cluttered experience
 **Ensure Website is Legitimate** | Basic | It may sound obvious, but when you logging into any online accounts, double check the URL is correct. When visiting new websites, look for common signs that it could be unsafe: Browser warnings, redirects, on-site spam and pop-ups. You can also check a website using a tool, such as: [Virus Total URL Scanner](https://www.virustotal.com/gui/home/url), [IsLegitSite](https://www.islegitsite.com), [Google Safe Browsing Status](https://transparencyreport.google.com/safe-browsing/search) if you are unsure
 **Watch out for Browser Malware** | Basic | Your system or browser can be compromised by spyware, miners, browser hijackers, malicious redirects, adware etc. You can usually stay protected, just by: ignoring pop-ups, be wary of what your clicking, don't proceed to a website if your browser warns you it may be malicious. Common sighs of browser malware include: default search engine or homepage has been modified, toolbars, unfamiliar extensions or icons,  significantly more ads, errors and pages loading much slower than usual. These articles from Heimdal explain [signs of browser malware](https://heimdalsecurity.com/blog/warning-signs-operating-system-infected-malware),  [how browsers get infected](https://heimdalsecurity.com/blog/practical-online-protection-where-malware-hides) and [how to remove browser malware](https://heimdalsecurity.com/blog/malware-removal)
-**Use a Privacy-Respecting Browser** | Recommended | [Firefox](https://www.mozilla.org/en-US/firefox/new) and [Brave](https://brave.com) are secure, private-by-default browsers. Both are fast, open source, user-friendly and available on all major operating systems. Your browser has access to everything that you do online, so if possible, avoid Google Chrome, Microsoft IE and Apple Safari as (without correct configuration) all three of them, collect usage data, call home and allow for invasive tracking.

+**Use a Privacy-Respecting Browser** | Recommended | [Firefox](https://www.mozilla.org/en-US/firefox/new) (with a few tweaks) and [Brave](https://brave.com) are secure, private-respecting browsers. Both are fast, open source, user-friendly and available on all major operating systems. Your browser has access to everything that you do online, so if possible, avoid Google Chrome, Edge and Safari as (without correct configuration) all three of them, collect usage data, call home and allow for invasive tracking. Firefox requires a few changes to achieve optimal security, for example - [arkenfox](https://github.com/arkenfox/user.js/wiki) or [12byte](https://12bytes.org/articles/tech/firefox/firefoxgecko-configuration-guide-for-privacy-and-performance-buffs/)'s user.js configs.

 **Use a Private Search Engine** | Recommended | Using a privacy-preserving, non-tracking search engine, will reduce risk that your search terms are not logged, or used against you. Consider [DuckDuckGo](https://duckduckgo.com), [Qwant](https://www.qwant.com), or [SearX](https://searx.me) (self-hosted). Google implements some [incredibly invasive](https://hackernoon.com/data-privacy-concerns-with-google-b946f2b7afea) tracking policies, and have a history of displaying [biased search results](https://www.businessinsider.com/evidence-that-google-search-results-are-biased-2014-10). Therefore Google, along with Bing, Baidu, Yahoo and Yandex are incompatible with anyone looking to protect their privacy. It is recommended to update your [browsers default search](https://duckduckgo.com/install) to a privacy-respecting search engine
 **Remove Unnecessary Browser Addons** | Recommended | Extensions are able to see, log or modify anything you do in the browser, and some innocent looking browser apps, have malicious intentions. Websites can see which extensions you have installed, and may use this to enhance your fingerprint, to more accurately identify/ track you. Both Firefox and Chrome web stores allow you to check what permissions/access rights an extension requires before you install it. Check the reviews. Only install extensions you really need, and removed those which you haven't used in a while
 **Keep Browser Up-to-date** | Recommended | Browser vulnerabilities are constantly being [discovered](https://cve.mitre.org/cgi-bin/cvekey.cgi?keyword=browser) and patched, so it’s important to keep it up to date, to avoid a zero-day exploit. You can [see which browser version your using here](https://www.whatismybrowser.com/), or follow [this guide](https://www.whatismybrowser.com/guides/how-to-update-your-browser/) for instructions on how to update. Some browsers will auto-update to the latest stable version
