With the introduction of the new Firefox Quantum browser in 2017, we changed the look, feel and performance of our main product. Since then, we have launched new products to complement your experience by using Firefox and serving beyond the browser. This includes Facebook Container, Firefox Monitor and Firefox Send. Together, they work to protect your privacy and keep you safe. We have been delivering that to you for over twenty years by placing your security and privacy first in the construction of products that are open and accessible to all.
The new version of Firefox today continues to meet quickly and privately at the crossroads of performance and security. It includes improvements that continue to keep Firefox at the same time that gives you more control and security through the new features that your personal information is safe while you are online with us.
To see how much faster Firefox is today:
How did we make Firefox faster?
To make Firefox faster, we simply prioritize our list of performance management "tasks". We apply many of the principles of time management, just as you could prioritize your own urgent needs. For example, before embarking on a road trip, verify that there is not a tank full of gasoline, that you have enough oil, or that you have adequate air pressure in your tires.
For this latest version of Firefox, we adopt the well-known strategy of time management or "postponement on purpose". The result is that Firefox is better to perform tasks at the optimal time. This is how we reorganize our to-do list to make Firefox faster:
- Depriorize the less used characteristics: We review the areas that we found that could be delayed and delivered by "painting" the page faster so you can navigate faster. This includes delaying the set time to prioritize the scripts for the things you need first, while delaying others so that the main Instagram, Amazon and Google scripts run between 40 and 80% faster; scanning for alternative stylesheets after loading the page; and do not load the autocomplete module unless there is a real form to complete.
- Suspend idle tabs: You should not feel guilty about opening a tab, but keeping those tabs open uses your computer's memory and slows down its performance. Firefox will now detect if your computer's memory is running low, which we define as less than 400MB, and suspend the unused tabs you have used or watched for a while. Rest assured that if you decide to revise that web page, simply click on the tab and it will reload where you left off.
- Fastest start after customization: For users who have customized their browser with an add-on as a favorite theme, for example, changing it to the seasons of the year, or using one of the popular ad blockers, we have made it so that the browser is sent out of unnecessary work during subsequent starts
New privacy protections
Privacy has always been central to Mozilla's mission, and the latest news and events have given people more reason to worry about their privacy while online. In 2018, we launched features focused on privacy, such as Opt-in Tracking Protection on the desktop, Default Tracking Protection on iOS and our popular Facebook Content Extension.
For today's release, we continue to provide you with privacy features and set up protections to help you feel safe online when you are with Firefox. Today's privacy features include:
- Blocking fingerprints and criptominium: In August 2018, we shared our approach tailored to the fight against tracking the growing consumer demand for features and services that respect online privacy. One of the three key areas we said was tackling harmful practices, such as the fingerprint that is based on the fingerprint that tracks it through the web, and the cryptomino that uses the power of your computer's CPU to generate the cryptocurrency. for the benefit of someone. Based on the recent tests of this function in our pre-release channels last month, today the Firefox version offers you the option to "change the switch" in the browser and protect yourself from these narrative practices.
- To activate this function in the small icon "i" in the address bar and under Content Lock, click on the custom gear on the right side. The other option is to go to your preferences. Click on Privacy and security on the left side. Blocking content listed at the top. Select Custom and check "Cryptominers" and "Fingerprinters" so that both are blocked.
- Customize your private browsing experience: Of the many types of privacy protections offered by Firefox, private browsing remains one of our most popular features. Private browsing removes cookies when you close the browser window and do not track history. In addition, private browsing also blocks tracking cookies by default. Based on user feedback, we offer more controls so you can get the most out of your private browsing experience.
- Saving passwords – Although you can enjoy private browsing, you may want some of the comfort of a typical Firefox experience. This included not having to write passwords every time you visit a site. At today's launch, you can visit a site in private browsing without the hassle of typing your password each time. Registering and saving passwords for a website in private browsing will work the same as in normal mode.
- Enable or disable add-ons / web extensions – As of today's release, you can now decide which extensions you want to enable or disable in private browsing. As part of installing an extension, Firefox will ask if it should be allowed to run in private browsing, with a default value or Do not allow. For extensions that have already installed this version, you can go to your Add-ons and enable or disable Private Browsing simply by clicking on the extension you want to manage.
Additional features at today's launch:
- Online accessibility for everyone – Mozilla has always strived to facilitate access to the web for everyone. We are happy to deploy a fully accessible browser toolbar from today's launch. To use this function, simply press the "tab" or "arrow" keys to reach the buttons on the far right of the toolbar, including its extension buttons, the toolbar overflow panel, and the Firefox main menu. This is just one more step to facilitate access to the web for everyone, no matter what their abilities are. To learn more about our work on accessibility, you can read more on our Citizen Internet blog.
- WebRender update – We will send WebRender to a small group of users, specifically to Windows 10 desktop users with NVIDIA graphics cards. Last year, we talked about the integration of WebRender, our next-generation GPU-based 2D rendering engine. WebRender will help make web browsing feel faster, more efficient and smoother by moving the central graphics processing processes to the Graphics Processing Unit. We are starting with this group of users and we plan to implement this feature throughout the year. To know more visit here.
- Smoother video playback with today's AV1 update – AV1 is the new royalty-free video format jointly developed by Mozilla, Google, Microsoft, Amazon and others as part of the Alliance for Open Media (AOMedia). First we provide AV1 support by sending the reference decoder in the Firefox version of January. The current version of Firefox is updated to use the newer, higher performance AV1 decoder known as dav1d. We have seen a great growth in the use of AV1 in just a few months, with our latest figures showing that 11.8% or video playback in Firefox Beta used AV1, an increase of 0.85% in February and 3% in March.
