Mozilla Firefox is one of the most popular browsers, both for its speed and its focus on privacy and security. But did you know that Firefox's security and privacy can be increased significantly beyond its default settings?<\/p>

We've prepared a few steps for you that will make using Firefox safer and more private. The instructions were created for Firefox\u00a0version 130<\/em><\/strong>, but they should also work in the future, on newer versions of the browser.<\/p>

We've divided each tip into two levels, depending on how many potential compatibility issues the setting may cause. If your goal is to browse the Internet carefree without any technical problems, we recommend that you aim for level 1. However, if you don't mind the occasional compatibility issue, level 2 will help you achieve a much higher level of security and privacy.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The uBlock Origin add-on blocks ads and unwanted elements on websites. It also complements Advanced Tracking Protection by blocking additional tracking elements. It protects you from potentially harmful ads. It is a non-commercial, community project with a good reputation, whose security and functionality is verified and controlled directly by Mozilla.<\/p>

You can install the uBlock Origin add-on at the following link:\u00a0https:\/\/addons.mozilla.org\/sk\/firefox\/addon\/ublock-origin\/<\/a>.<\/span><\/p>

After installing the add-on, we also recommend enabling it in private windows as follows: Firefox browser menu in the upper right corner\u00a0\u2192 Settings \u2192 Extensions and themes<\/em><\/strong>\u00a0in the lower left corner\u00a0\u2192<\/em><\/strong>\u00a0click on the uBlock Origin inscription \u2192 Enable in private windows\u00a0\u2192<\/em><\/strong>\u00a0switch to\u00a0\"Enable\"<\/em><\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Startpage.com is an internet search engine originating from the Netherlands, which prides itself on its strict privacy policies for its users. Unlike search engines such as Google or Bing, Startpage.com does not store your queries, does not record your IP address and does not use any tracking cookies.<\/p>

A big advantage of the Startpage.com search engine compared to, for example, DuckDuckGo is the fact that its search results are taken from the Google search engine. This way, you get relevant and accurate results, but not at the expense of your privacy.<\/p>

You can install the Startpage search engine at the following link:\u00a0https:\/\/addons.mozilla.org\/en-US\/firefox\/addon\/startpage-private-search\/<\/a>.<\/span><\/p>

You can activate it as the default search engine as follows: Firefox browser menu in the upper right corner\u00a0\u2192 Settings \u2192 Search \u2192 Default search engine \u2192<\/em><\/strong>\u00a0switch to \"Startpage.com\".<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
