Mozilla Firefox is one of the world's most famous and used browsers. It is a program that stands out in the first instance because it is completely free in its full version, in addition to being open-source software, that is, users can make all kinds of modifications to the source code to adapt it to their tastes or needs.

Customization is another of the fundamental aspects of this browser, considering that we can add many options to the initial tools through extensions to configure it as we like. Mozilla offers a wide variety of extensions for your browser right now, but the utility of each is specific in many cases, ideal for entertainment or work.

The navigation in this program occurs through the already classic mechanism of tabs that we can organize as we like. This way, you can open each page in a new window or simply in tabs to easily access them. And you also can open Incognito windows so that the navigation is not stored in the history, and nobody knows then what sites you have been visiting.

The synchronization of this program with Google, the world's main search engine, is another aspect you cannot lose sight of. From the Home page, you can establish this search engine as a source for each word or phrase you enter. This way, opening the official Google website to search for content is unnecessary.

This web browser also allows users to establish all shortcuts, perfect for saving time if you usually repeat actions. You can use keyboard shortcuts to items such as the Downloads, the marked pages, History, Add-ins, synchronized items, and many more.

But to these basic functionalities, others are added, for example, an integrated spell-checker and a PDF reader also integrated into its original version. Do you want to read at night or on public transport? You can take advantage of the Reading Mode, which simplifies the text so that the experience is much closer to the books. And if you are looking for something close to home, do not forget the navigation system with geolocation active.

Security is another of the areas on which the developers of Firefox have worked. We find ourselves with an integrated pop-up blocker and all kinds of options perfect for protecting our privacy. As mentioned before, the private browsing mode will allow you to rest assured that no one else knows which sites you visit.

At the same time, Firefox has a security system responsible for registering the websites you visit to offer information and alerts if it is considered unreliable in managing personal or compromising data. And if you add that security updates are constant for this browser, you can visit your favorite sites without worrying about cybercriminals.

This browser interface deserves a separate chapter. We find one that, although it is simple at first, we can customize to the maximum. As part of this setup process, it is possible to modify the available themes, which change a good part of the visual aspect of the software. In turn, the integrated functions of the menu can also be organized as you consider more comfortable.

As for the Firefox Add-ons, we can say that some of them have become almost indispensable for most users. Suppose you are tired of receiving all kinds of annoying advertising when you visit websites of your preference. In that case, you will probably find Adblock Plus an excellent alternative to end these pop-up windows that will not leave you alone for even a minute.

Not long ago, Firefox added a service called Firefox Hello, a system of internal chats similar to the old chat rooms that were all the rage several years ago. It has a function similar to HANGOUTS. This way, you can send all your friends quickly and easily the web page you are viewing to access it directly.

Synchronization between devices Without a doubt, this is another of those functions of the Mozilla browser that we recommend worldwide. If you have reviewed some sites in the morning in the application of this browser on your mobile, synchronize your account both on the phone and on your computer to be able to send you absolutely all that information so you can continue reading that interesting article that you have left pending.

We did not want to complete this description without discussing the integrated password management system with Mozilla Firefox. The Password Manager of this software saves all your passwords so you can automatically log in, something that we know that many users, especially those with multiple accounts on websites and social networks, will be grateful for.

And finally, we have the Bookmarks. These websites, we can save and organize in the way that we like the most through the famous Bookmarks of this browser have been a distinctive sign of the browser since its appearance. From the star icon located at the top right of the screen, you can save all our sites, add annotations, sort them into folders, and much more!
