Firefox 35 Download

The official release date of Firefox 35 is January 13, 2015. Firefox releases are always pushed to the official Mozilla ftp server before the official release data and distributed to mirror sites around the globe to ensure that the update runs flawlessly for all users of the browser.

While it may be tempting to download that version, last minute changes may require that another build gets released as the final version. It is therefore best to wait until the release is announced officially by Mozilla.

Most Firefox users will receive the update via the browser's built-in update module. Users who prefer to download it instead can do so on the official Mozilla website.

Firefox 35 Changes

Firefox 35 ships with new and improved features. While that is the case, it appears to be a minor release feature-wise both on the desktop as well as on mobile.

Firefox Hello with room functionality

Rooms extend the functionality of Firefox Hello, the real-time video and audio chat module of Firefox that Mozilla introduced in Firefox 34.

It works similar to chat rooms that persist even if the initiator of a connection closes Firefox or the Hello module.

Rooms are limited and not comparable to IRC chat and other chat rooms where dozens or even hundreds of users communication with each other.

From initial tests, it looks as if rooms are limited to 2 participants.

Additional information about Firefox Hello are available on Mozilla Support.

HTTP Public Key Pinning Extension implemented

Public Key Pinning was introduced in Firefox 32 on the desktop and in Firefox 34 for Android. The security feature links specific domains and services to Certificate Authorities (CAs) so that they are used instead of authorities that are not mentioned.

The Public Key Pinning Extension provides site owners to do the same on their end. It allows them to list acceptable Certificate Authorities that browsers should use during connection to reduce the impact of compromised Certificate Authorities.

Public Key Pinning Extension requires an initial connection to the site in order to get the pinset from it which it wants the browser to use in future connections.

It is possible to change the order of search engines now. You need to open the Search Options for that and use drag and drop operations to reorder the search engines. Check out this guide if you want to restore the old search interface in Firefox.
