Tomorrow it opens Firefox 135 with a set of new features that reinforce its position as one of the most versatile and secure browsers. One of the most notable improvements is the expansion of language support in the built-in translation feature, which now allows for the translation of pages in Simplified Chinese, Japanese and Korean, as well as offering Russian as a target language. This significantly expands the options for users who rely on machine translation to access content in other languages.
Another important update is the gradual expansion of credit card auto-fill to all users worldwide, making online shopping faster and safer. Additionally, access to the AI Chatbot is also in the process of being rolled out globally, which will allow users to interact with this optional feature through the sidebar or Firefox Labs, selecting the provider of their choice for a personalized experience.
Other new features in Firefox 135
In terms of security, Firefox 135 implements the certificate transparency, forcing web servers to provide proof of public disclosure before being trusted. Along with this, the progressive implementation of the CRLite revocation mechanism will improve the speed and efficiency of certificate verification, reducing the impact on browser performance.
To improve the browsing experience, Firefox introduces History API Abuse Protections, preventing sites from generating excessive input that can make it difficult to use the back and forward navigation buttons. On macOS and Linux, users can now close only the active tab by using the exit keyboard shortcut, rather than closing the entire window when multiple tabs are open.
The new tab design also receives improvements, globally extending the changes introduced in Firefox 134 to users in the United States. Now, the Logo has been repositioned to prioritize Web Search, Shortcuts, and Recommended Stories, as well as allowing up to four columns on large screens. Another visual improvement is the renaming of the “Copy without site tracking” menu option to “Copy clean link,” making it clearer that it is intended to remove known tracking parameters from links, a feature that is now also available for plain text links.
New packaging for your binaries
Linux users will notice that Binaries are now provided in XZ format instead of BZ2, which improves unpacking speed and reduces file sizes. Additionally, support for a post-quantum key exchange mechanism (mlkem768x25519) for HTTP/3 has been added, strengthening the browser's security against future threats.
On the development side, attribute values for PointerEvent coordinates can now be fractional rather than integer, allowing for greater precision on CSS-animated elements or zoomed windows. Events such as mouseenter and pointerenter have also been improved to better meet specifications, and support has been added for the WebAuthn getClientCapabilities() method. Developers will also receive a warning when applying content-visibility on elements without size containment, and can use the new $$$ console command to search for content within shadow roots. Additionally, WebExtensions debugging has been improved, with an optimized context selector for workers and content scripts.
Finally, improvements have been made to the translation system to reduce the generation of made-up words in certain situations, and several security vulnerabilities have been fixed. Firefox 135 promises to remain a solid choice for those looking for a fast, secure, and ever-evolving browser.
