Mozilla Firefox Version


Six weeks after the release of Firefox 6, Mozilla officially released the new next version for Firefox. The seventh cycle of development confirms the rapid release schedule adopted by Mozilla this year. While there are rumors regarding the idea of shortening this cycle to only five weeks, these won’t happen too soon.

Similar to its previous version, Firefox 7 brings few notable improvements and features. The most important improvement is the memory usage optimization. It is said that Firefox 7 has reduced its memory usage by 20% and even 50% in special cases. This comes as a positive effect for the startup and page loading times, which suffered a lot in previous version.

Firefox makes it to version 54, Mozilla dubs it 'the best Firefox' Mozilla has announced the latest update to its popular web browser. Firefox is now up to version number 54 with changes that, according to the company, make it 'the best Firefox in history' thanks to an important performance tweak in the form of multiprocess support when loading tabs. Firefox release notes are specific to each version of the application. Select your version from the list below to see the release notes for it.

Mozilla Firefox Version 60

Mozilla has also tweaked the Javascript module in order to free up memory no longer in use. In this way, they have addressed one of the oldest issues present in previous Firefox versions. No you can let the browser run as much as you want without noticing any expense in system resources. For example is enough to close unused tabs in order to free up memory, and this without the need to restart the browser.

Mozilla Firefox is multi-platform, and it is available for both desktop and mobile devices. Its desktop version is supported for Windows, Mac, and Linux operating systems. For mobile, it is supported for both Android and iOS with the apps Firefox for Android and Firefox for iOS, respectively. Data can be synced between Firefox versions across.

Other subtle improvements have been done to the Firefox Sync component which now initializes the sync process for password and bookmark changes more frequently as they are modified or added. Firefox 7 also adds support for CSS3 Text Overflow method and a new measurement tool that allows web developers to identify performance improvements or flaws on their website.

Azure is the new graphical component introduced in Firefox 7 in order to improve the rendering process of Canvas present in the new HTML 5 standard. In this way Mozilla is trying to prepare its path for future worldwide changes in the HTML standard. A subtle but good change has been applied to the address bar. Now the main domain from a web address is even more highlighted compared to the subdomain component and the “http://” prefix is not visible anymore.

Pluses: faster than previous versions especially on complex web-pages, support for CSS3 Text Overflow, fast Canvas rendering with Azure component, faster Firefox Sync option, less memory leak;
Drawbacks/flaws: third party extensions cannot keep up with the rapid cycle of development from Mozilla;
In conclusion: With version 7, the Mozilla team is continuing its optimization process to improve and bring Firefox to the next level of quality.

  • 1Recommended configurations
The goal of this document is to help operational teams with the configuration of TLS. All Mozilla websites and deployments should follow the recommendations below.

Mozilla maintains this document as a reference guide for navigating the TLS landscape, as well as a configuration generator to assist system administrators. Changes are reviewed and merged by the Mozilla Operations Security and Enterprise Information Security teams.

Updates to this page should be submitted to the server-side-tls repository on GitHub. Issues related to the configuration generator are maintained in their own GitHub repository.

In the interests of usability and maintainability, these guidelines have been considerably simplified from the previous guidelines.

The Mozilla SSL Configuration Generator
Mozilla maintains three recommended configurations for servers using TLS. Pick the correct configuration depending on your audience:

  • Modern: Modern clients that support TLS 1.3, with no need for backwards compatibility
  • Intermediate: Recommended configuration for a general-purpose server
  • Old: Services accessed by very old clients or libraries, such as Internet Explorer 8 (Windows XP), Java 6, or OpenSSL 0.9.8
Configuration Firefox Android Chrome Edge Internet Explorer Java OpenSSL Opera Safari
Modern 63 10.0 70 75 -- 11 1.1.1 57 12.1
Intermediate 27 4.4.2 31 12 11 (Win7) 8u31 1.0.1 20 9
Old 1 2.3 1 12 8 (WinXP) 6 0.9.8 5 1

The ordering of cipher suites in the Old configuration is very important, as it determines the priority with which algorithms are selected.

OpenSSL will ignore cipher suites it doesn't understand, so always use the full set of cipher suites below, in their recommended order. The use of the Old configuration with modern versions of OpenSSL may require custom builds with support for deprecated ciphers.

Modern compatibility

For services with clients that support TLS 1.3 and don't need backward compatibility, the Modern configuration provides an extremely high level of security.

  • Cipher suites (TLS 1.3): TLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256
  • Cipher suites (TLS 1.2): (none)
  • Protocols: TLS 1.3
  • Certificate type: ECDSA (P-256)
  • TLS curves: X25519, prime256v1, secp384r1
  • HSTS: max-age=63072000 (two years)
  • Certificate lifespan: 90 days
  • Cipher preference: client chooses
  • Rationale:
    • All cipher suites are forward secret and authenticated
    • The cipher suites are all strong and so we allow the client to choose, as they will know best if they have support for hardware-accelerated AES
    • We recommend ECDSA certificates using P-256, as P-384 provides negligible improvements to security and Ed25519 is not yet widely supported

Intermediate compatibility (recommended)

For services that don't need compatibility with legacy clients, such as Windows XP or old versions of OpenSSL. This is the recommended configuration for the vast majority of services, as it is highly secure and compatible with nearly every client released in the last five (or more) years.

  • Cipher suites (TLS 1.3): TLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256
  • Protocols: TLS 1.2, TLS 1.3
  • TLS curves: X25519, prime256v1, secp384r1
  • Certificate type: ECDSA (P-256) (recommended), or RSA (2048 bits)
  • DH parameter size: 2048 (ffdhe2048, RFC 7919)
  • HSTS: max-age=63072000 (two years)
  • Certificate lifespan: 90 days (recommended) to 366 days
  • Cipher preference: client chooses

Mozilla Firefox Version 2.0

  • Rationale:
    • All cipher suites are forward secret and authenticated
    • TLS 1.2 is the minimum supported protocol, as recommended by RFC 7525, PCI DSS, and others
    • ECDSA certificates are recommended over RSA certificates, as they allow the use of ECDHE with Windows 7 clients using Internet Explorer 11, as well as allow connections from IE11 on Windows Server 2008 R2
    • The cipher suites are all strong and so we allow the client to choose, as they will know best if they have support for hardware-accelerated AES
    • Windows XP (including all embedded versions) are no longer supported by Microsoft, eliminating the need for many older protocols and ciphers
    • Administrators needing to provide access to IE 11 on Windows Server 2008 R2 and who are unable to switch to or add ECDSA certificates can add TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA
    • While the goal is to support a broad range of clients, we reasonably disable a number of ciphers that have little support (such as ARIA, Camellia, 3DES, and SEED)
    • 90 days is the recommended maximum certificate lifespan, to encourage certificate issuance automation

Mozilla Firefox Version

Old backward compatibility

Mozilla Firefox Version 48

This configuration is compatible with a number of very old clients, and should be used only as a last resort.

  • Cipher suites (TLS 1.3): TLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256
  • Protocols: TLS 1.0, TLS 1.1, TLS 1.2, TLS 1.3
  • TLS curves: X25519, prime256v1, secp384r1
  • Certificate type: RSA (2048-bits)
  • Certificate curve: None
  • DH parameter size: 1024 (generated with openssl dhparam 1024)
  • HSTS: max-age=63072000 (two years)
  • Certificate lifespan: 90 days (recommended) to 366 days
  • Cipher preference: server chooses
  • Rationale:
    • Take a hard look at your infrastructure needs before using this configuration; it is intended for special use cases only
    • If possible, use this configuration only for endpoints that require it, segregating it from other traffic
    • SSLv3 has been disabled entirely, ending support for older Windows XP SP2 clients. Users requiring support for Windows XP SP2 may use previous versions of this configuration, with the caveat that SSLv3 is no longer safe to use
    • This configuration requires custom builds to work with modern versions of OpenSSL, using enable-ssl3, enable-ssl3-method, enable-deprecated, and enable-weak-ssl-ciphers
    • Most ciphers that are not clearly broken and dangerous to use are supported

Mozilla also maintains these recommendations in JSON format, for automated system configuration. This location is versioned and permanent, and can be referenced in scripts and tools. The file will not change, to avoid breaking tools when we update the recommendations.

We also maintain a rolling version of these recommendations, with the caveat that they may change without warning and without providing backwards compatibility. As it may break things if you use it to automatically configure your servers without review, we recommend you use the version-specific file instead.
