This is a list of free and open source internet software (Internet browsers, e-mail clients, File sharing, FTP, remote access, messengers...).
- Mozilla Firefox
Mozilla Firefox, or simply Firefox, is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, Mozilla Corporation. Firefox uses the Gecko layout engine to render web pages, which implements current and anticipated web standards. In 2017, Firefox began incorporating new technology under the code name Quantum to promote parallelism and a more intuitive user interface. Firefox is officially available for Windows 7 or newer, macOS, and Linux. Its unofficial ports are available for various Unix and Unix-like operating systems including FreeBSD, OpenBSD, NetBSD, illumos, and Solaris Unix. Firefox is also available for Android and iOS, however the iOS version uses the WebKit layout engine instead of Gecko due to platform limitations, as with all other iOS web browsers.
Features include tabbed browsing, spell checking, incremental search, live bookmarking, Smart Bookmarks, a download manager, private browsing, location-aware browsing (also known as "geolocation") based on a Google service, and an integrated search system, which uses Google by default in most markets. Additionally, Firefox provides an environment for web developers in which they can use built-in tools, such as the Error Console or the DOM Inspector, or extensions, such as Firebug and more recently there has been an integration feature with Pocket. Firefox Hello was an implementation of WebRTC, added in October 2014, which allows users of Firefox and other compatible systems to have a video call, with the extra feature of screen and file sharing by sending a link to each other. Firefox Hello was scheduled to be removed in September 2016.
- Google Chrome
Google Chrome is a cross-platform web browser developed by Google. It was first released in 2008 for Microsoft Windows, and was later ported to Linux, macOS, iOS, and Android. The browser is also the main component of Chrome OS, where it serves as the platform for web apps.
Most of Chrome's source code comes from Google's open-source Chromium project, but Chrome is licensed as proprietary freeware. WebKit was the original rendering engine, but Google eventually forked it to create the Blink engine; all Chrome variants except iOS now use Blink.
Google Chrome features a minimalistic user interface, with its user-interface principles later being implemented into other browsers. For example, the merging of the address bar and search bar into the omnibox. Chrome also has a reputation for strong browser performance.
Chrome allows users to synchronize their bookmarks, history, and settings across all devices with the browser installed by sending and receiving data through a chosen Google Account, which in turn updates all signed-in instances of Chrome.
Yandex Browser is a freeware web browser developed by the Russian web search corporation Yandex that uses the Blink web browser engine and is based on the Chromium open source project. The browser checks webpage security with the Yandex security system and checks downloaded files with Kaspersky anti-virus. The browser also uses Opera Software's Turbo technology to speed web browsing on slow connections.
The browser is available for Windows, macOS, Android and iOS. In October 2014 a Linux beta version was introduced.
Yandex is facing web search competition in Russia from Google Search. Google Chrome, Russia's most popular web browser, uses Google Search as its default search engine. In June 2012, Mozilla Firefox, the world's third most popular web browser, signed a deal to replace its default search engine Yandex Search with Google Search. As Yandex Browser's "Smartbox" uses Yandex Search as its default search engine, the browser will help Yandex compete for Russian search market share.
Distinguishing features of the Yandex Browser include the following:
- Different "new tab" screen with a Windows 8-style interface and specialized widgets for popular services (e.g., the gmail widget shows number of unread messages).
- Accept browser extensions from the Opera add-ons website.
Opera is a freeware web browser for Microsoft Windows, Android, iOS, macOS, and Linux operating systems, developed by Opera Software. Opera is a Chromium-based browser using the Blink layout engine. It differentiates itself because of a distinct user interface and other features.
There are also three mobile versions called Opera Mobile, Opera Touch, and Opera Mini.
Opera has originated features later adopted by other web browsers, including: Speed Dial, pop-up blocking, re-opening recently closed pages, private browsing, and tabbed browsing. Opera includes a bookmarks bar and a download manager. Opera also has "Speed Dial", which allows the user to add an unlimited number of pages shown in thumbnail form in a page displayed when a new tab is opened. Speed Dial allows the user to more easily navigate to the selected web pages.
It is possible to control some aspects of the browser using the keyboard shortcuts. Page zooming allows text, images and other content such as Adobe Flash Player, Java platform and Scalable Vector Graphics to be increased or decreased in size to help those with impaired vision.
Opera Software claims that when the Opera Turbo mode is enabled, the compression servers compress requested web pages (except HTTPS pages) by up to 50%, depending upon the content, before sending them to the users.
One security feature is the option to delete private data, such as HTTP cookies, browsing history, items in cache and passwords with the click of a button. This lets users erase personal data after browsing from a shared computer.
- Mozilla Thunderbird
Mozilla Thunderbird is a free and open-source, cross-platform email client, news client, RSS, and chat client developed by the Mozilla Foundation. The project strategy was modeled after that of the Mozilla Firefox web browser. It is installed by default on Ubuntu desktop systems.
Thunderbird is an email, newsgroup, news feed, and chat (XMPP, IRC, Twitter) client. The vanilla version was not originally a personal information manager (PIM), although the Mozilla Lightning extension, which is now installed by default, adds PIM functionality. Additional features, if needed, are often available via other extensions.
Thunderbird can manage multiple email, newsgroup, and news feed accounts and supports multiple identities within accounts. Features such as quick search, saved search folders ("virtual folders"), advanced message filtering, message grouping, and labels help manage and find messages.
Thunderbird incorporates a Bayesian spam filter, a whitelist based on the included address book, and can also understand classifications by server-based filters such as SpamAssassin.
Extensions allow the addition of features through the installation of XPInstall modules (known as "XPI" or "zippy" installation) via the add-ons website that also features an update functionality to update the extensions.
Thunderbird runs on a variety of platforms. Releases available on the primary distribution site support the following operating systems: Linux, Windows, macOS.

Skype (/skaɪp/) is a telecommunications application that specializes in providing video chat and voice calls between computers, tablets, mobile devices, the Xbox One console, and smartwatches via the Internet. Skype also provides instant messaging services. Users may transmit text, video, audio and images. Skype allows video conference calls.
Skype allows users to communicate over the Internet by voice, using a microphone, by video using a webcam, and by instant messaging. Skype implements a freemium business model. Skype-to-Skype calls are free of charge, while calls to landline telephones and mobile phones (over traditional telephone networks) are charged via a debit-based user account system called Skype Credit. Some network administrators have banned Skype on corporate, government, home, and education networks, citing such reasons as inappropriate usage of resources, excessive bandwidth usage and security concerns.
- Tox - Open source Skype alternative
Whether it's corporations or governments, digital surveillance today is widespread. Tox is easy-to-use software that connects you with friends and family without anyone else listening in. While other big-name services require you to pay for features, Tox is completely free and comes without advertising — forever.
Tox began a few years ago, in the wake of Edward Snowden's leaks regarding NSA spying activity. The idea was to create an instant messaging application that ran without requiring the use of central servers. The system would be distributed, peer-to-peer, and end-to-end encrypted, with no way to disable any of the encryption features; at the same time, the application would be easily usable by the layperson with no practical knowledge of cryptography or distributed systems. During the Summer of 2013 a small group of developers from all around the globe formed and began working on a library implementing the Tox protocol. The library provides all of the messaging and encryption facilities, and is completely decoupled from any user-interface; for an end-user to make use of Tox, they need a Tox client. Fast-forward a few years to today, and there exist several independent Tox client projects, and the original Tox core library implementation continues to improve. Tox (both core library and clients) has thousands of users, hundreds of contributors, and the project shows no sign of slowing down.
Tox is a FOSS (Free and Open Source) project. All Tox code is open source and all development occurs in the open. Tox is developed by volunteer developers who spend their free time on it, believing in the idea of the project. Tox is not a company or any other legal organization. Currently we don't accept donations as a project, but you are welcome to reach out to developers individually.
