After months of development, Mozilla has released the redesigned version of Firefox. This update aims to modernize the browser and strengthen its ability to compete with the market leader, Google Chrome, according to Ajit Varma, who is responsible for the Firefox division.
In a conversation with Ars Technica, the executive detailed that this new phase of the browser seeks to be chosen by users not only as an alternative to Chromium but because it possesses features that make it more attractive than competing browsers.
It is important to note the technical distinction: Chrome uses the open-source Chromium project, to which resources developed by Google are added. A fundamental component of Chromium is Blink, the rendering engine that converts a webpage's source code into visual content for the user.
Chromium serves as the basis for several other browsers, including Microsoft Edge, Opera, Vivaldi, and Brave. Firefox, however, differs by employing Gecko, a rendering engine created by Mozilla itself.
Varma admitted that a large part of Firefox users use it simply because they want an option not based on Chromium. However, with the browser's renewal, the expectation is to attract users who choose Firefox due to its functionalities. He stressed that few people are interested in or understand the technical debate between 'Chromium vs. Gecko.'
This situation represents an opportunity for differentiation from Chromium-based browsers. When analyzing these projects, a great similarity is perceived, as it is simpler to create a *fork* and apply superficial modifications than to implement deeper changes. However, Mozilla has the advantage of controlling the entire structure, allowing for bolder changes.
He noted that it is necessary to reach a wider audience, one that is not restricted only to well-informed individuals, targeting a massive public indifferent to the difference between Gecko and Chromium.
The task is not simple, given that Chrome leads in the number of users by habit, and not necessarily by functional superiority. Mozilla's purpose with the new Firefox is to make it functionally attractive, causing users to stop, observe, and decide to use it based on the new attributes.
Firefox 157 was launched on Tuesday, September 29th, presenting a new visual standard. This design change encompasses rounded formats for bars, fields, and buttons, adjustments to spacing between visual elements, in addition to introducing new color schemes and themes, following the Project Nova design.
In terms of features, the new version brings back compact mode (ideal for smaller screens) and reinforces security and privacy aspects, such as integrated VPN and support for the Manifest V2 standard to enable ad blockers (a feature discontinued by Chrome), in addition to offering new customization options.
Mozilla also emphasizes performance optimization. Although Varma did not notice differences in this aspect, he warned that the new phase of Firefox is just beginning, indicating that additional improvements may be implemented in future versions.
