What is a web browser tool?

A web browser tool is a software that lets you access and view web pages and websites. It is your main way of connecting to the Internet and exploring all the pages it offers.

How does a web browser work?

A web browser works by reading the instructions in the HTML/CSS and JavaScript files of the web pages, and then rendering the content on the screen as text, images, audio, video, and other files such as PDFs or interactive charts.

Different web browsers may use different versions of HTML, and that’s why a website may look different depending on the browser. There are many browsers available on the market, and most of them are free or open source. Privacy is often one of the most important features that users look for in web browsers.

You can switch browsers anytime, and you can install more than one on the same computer or smartphone.

The best web browsers for Portable

Some of the best web browsers for surfing the web are Google Chrome, Mozilla Firefox, Microsoft Edge (formerly Internet Explorer), Safari, Brave, Opera, Tor Browser, Vivaldi or Sidekick. The user interface is usually customizable, so you can make navigation easier with user-friendly interfaces. Web browsers let you access the Internet on desktop (Windows, macOS or Linux) as well as on mobile (iOS, Android) with mobile versions.

Web browsers offer a range of features that enhance your online experience, such as:

  • Tabs: You can keep multiple tabs open at the same time to switch between websites without losing your place.
  • Passwords: The web browser can securely store your passwords (with your consent) and fill them in automatically when you visit the same site again.
  • Security: Most web browsers Portable update regularly and automatically to protect you from malicious attacks and prevent security breaches. They also have other features like pop-up blocking and warning you when you visit a potentially unsafe site or download something suspicious.
  • Privacy: To protect your personal data, browsers let you manage how they track ads and cookies, and use private browsing mode.
  • Shortcuts/favorites: You can add several sites to a list of favorites or bookmarks, so you can access them faster, without using a search engine.
  • Web extensions: Browsers usually let you add custom extensions or plugins, such as ad blockers, productivity tools (screen capture, file converter, translator, etc.) and development tools, or extensions for videoconferencing tools.
  • Downloads: You can download items from websites through the browser.
  • PDF: You can view, edit and share PDFs directly from web browsers.
  • VPN: Some browsers, like Opera or Sidekick, have a built-in VPN to protect your personal information while browsing the web.
  • Browsing data: Browsers let you view your history, and manage or delete your browsing data.
  • Address bar: You can access websites directly from the browser’s address bar, which lets you type the exact address of a site, or keywords that will start a search on your default search engine.

Choose a web browser

Browsers are constantly updated to improve their speed and compatibility with the latest versions of websites. To select your browser, you need to consider your preferences in terms of privacy protection, plugin, speed and compatibility. It is possible that some old browsers are not able to support some new versions of sites. Sometimes technologies change, and browsers and sites have to adjust, as it happened with the end of Adobe Flash Player. Mobile browsers can be downloaded from the various stores, or are sometimes preinstalled, like Safari at Apple for example.
