10 Best Free Firefox Based Browsers For Windows

Here is a list of best free Firefox based browsers for Windows. Firefox based browsers basically use Firefox features and source code at their core. Developers of these browsers just add or remove some existing features from Firefox to build a new browser according to their requirements.

A more secure Firefox.

Download Firefox — English (US)

Users on 64-bit Windows who download Firefox can get our 64-bit version by default. That means you get a more secure version of Firefox, one that also crashes a whole lot less. How much less? In our tests so far, 64-bit Firefox reduced crashes by 39% on machines with 4GB of RAM or more.

What’s the difference between 32-bit and 64-bit?

Here’s the key thing to know: 64-bit applications can access more memory and are less likely to crash than 32-bit applications. Also, with the jump from 32 to 64 bits, a security feature called Address Space Layout Randomization (ASLR) works better to protect you from attackers. Linux and macOS users, fret not, you already enjoy a Firefox that’s optimized for 64-bit.

How do you get 64-bit Firefox?

If you’re running 64-bit Windows (here’s how to check), your Firefox may already be 64-bit. Check your Firefox version (in the “About Firefox” window) and look for “(32-bit)” or “(64-bit)” after the version number:

• If you see “(32-bit)” and you are running Firefox 56.0 or older, updating to the latest Firefox version should automatically upgrade you to 64-bit.
• If you see “(32-bit)” and are running Firefox 56.0.1 or newer, then your computer may not meet the minimum memory requirement for 64-bit (3 GB RAM or more). You can still manually install 64-bit Firefox, if you choose.

If you need to run 32-bit Firefox or manually install 64-bit Firefox, you can simply download and re-run the Windows (32-bit or 64-bit) Firefox installer from the Firefox platforms and languages download page.

Mozilla Firefox

Нужен быстрый, настраиваемый под индивидуальные нужды браузер? – предлагаем скачать Mozilla Firefox. Утилита представляет собой ядро, возможности которого легко расширить с помощью многочисленных плагинов, например: VKdownloader, AdBlock, YouTube High Definition и прочие. Скорость браузера на высоте – процент возникновения сбоев на 3% ниже, чем у ближайших конкурентов, что подтвердила Sauce Labs. Firefox построен на открытом портируемом движке Gecko, который работает на большинстве платформ: GNU, Mac OS X, FreeBSD, Microsoft Windows, Android, Linux и других.

Локализация

Проект был основан в США двумя сотрудниками Netscape Communications, одной из крупнейших корпораций IT-индустрии. Первый запуск состоялся в 2002 году. С того времени браузер стал самым популярным в Германии – его доля составляет около 40%. В России Firefox занял второе место, уступив лишь Google Chrome. На мировой арене лидером, как ни странно, является IE от Microsoft. На официальном сайте представлены файлы локализации для любой языковой категории планеты. Русскоговорящие пользователи могут Firefox на русском скачать бесплатно.

Мировой рейтинг наиболее распространенных программ для просмотра веб-страниц, по данным StatCounter, выглядит следующим образом:

1. Google Chrome – лидирует в странах Северной и Южной Америки, Восточной Европы.
2. Internet Explorer – занимает 90% рынка Китая, Японии и Южной Кореи.
3. Mozilla Firefox – наиболее распространен в Индонезии, Германии, некоторых странах Азии и Европы.
4. Opera – широко распространен в странах Африки.

Быстрый, гибкий, надежный и самый безопасный – сильные черты

Браузер Firefox признан самой безопасной программой для работы с интернетом – был создан для защиты приватности. Любая современная утилита сохраняет все действия, которые пользователь совершает в интернете. Это обусловлено удобством. Но не каждый хочет, чтобы действия отслеживались – это было учтено разработчиками. Впервые в браузер внедрен режим «Приватный просмотр», исключающий сохранение посещенных сайтов и страниц, чтобы его включить или выключить, достаточно нажать одну кнопку.
Как и любой другой браузер, Mozilla может сохранять логины и пароли пользователей для онлайн-сервисов. Если одним компьютером пользуется несколько человек, возникает риск. Для этого было внедрено расширение «Мастер паролей». Суть его работы такова – человек при запуске браузера вводит единый идентификатор, который открывает личные данные доступа от всех сайтов, проще говоря – все ваши пароли и логины защищены одним кодом.
