From the user’s point of view, and beyond all the aesthetical changes made to its interface, Firefox Quantum works like any other web browser. In other words, you only have to type an URL into the address bar and you’ll be taken straight to the web page in question. The thing is that certain changes have been made to the internal structure of the development, that have to do with its multiprocess functioning and, therefore, the processes are now managed in a different manner.
These changes in Firefox Quantum have mainly affected the CSS engine, also known as Stylo, which is totally new and has improved the performance of previous versions thanks to the fact that it makes the most of the features of modern hardware, allowing us to open parallel processes and making the most of the multiple cores of the processors. Now each open tab is treated like an independent process, which improves the global stability of Firefox and optimizes its different resources. In this aspect, we also have to point out that the priority is given to the active tab at each moment, allocating more system resources to that specific one than to the others.
In turn, Google has become the preset search engine, although there are over 60 different search engines available that can be used in the more than 90 languages that Firefox Quantum has been translated into.
All these changes that revolve around making the most of the system’s hardware resources have been focused on achieving a lower processor and memory consumption: the result is definitely a higher browsing speed.
