Mozilla Firefox is a highly customizable open source Internet browser which offers full-featured tools for improving your experience surfing the web. This application update has introduced several new features such as enhanced performance and anti-phishing security in order to protect your personal information against possible menaces. The new user interface is something fresh compared to other browsers, thanks to its new tab-browsing features and the great number of compatible add-ons.

Mozilla Firefox has made some changes from the previous version. It's developers have created a browser compatible with the latest web technologies in order to improve Firefox’s capabilities. HTML5, HD video content and high quality audio now work natively. It's streamlined design tries to display all kind of elements neatly, and also allows personalization using free third-party downloadable add-ons that enhance the functions of Mozilla Firefox.

The pop-up blocker helps users eliminate the constant annoyance of advertisement windows that may appear whilst you visit your favorite webpages. The new way of grouping different tabs into a new window is more visual, just like the general application which has become more intuitive with more popular functions. Because of these improvements in performance and security features, we can say that Mozilla Firefox is a powerful and recommendable option for your computer.

Not only for users but also for developers

The philosophy of Mozilla is clear in this aspect: open source is better for the community. In that sense, they have included some tools that will help developers to create more online content such as WebGL for 3D graphics, new ES6 functions for online applications or support for background-attachment, and local for having more control about scrolling elements. You can develop different kinds of add-ons in case you want to collaborate with Mozilla’s community, thereby increasing the functionality of the software. It also includes Scratchpad for testing Javascript snippets quickly and directly with Mozilla Firefox.

For users, security which features with anti-malware features is a relief regarding external viruses or to protect your own privacy. The navigation in protected websites (HTTPs) has been reinforced, securing your connections to those kinds of servers. The bookmarks section has also been modified, allowing better management of the websites you include on the list. Besides, you can configure Mozilla Firefox to read RSS feeds by selecting this add-on in the Preferences menu. That way, the toolbar will appear to the side. You can also update the application automatically in order to save time looking for new versions in the future.
