Mozilla & Netscape Code Signing Certificates

Code Signing for Mozilla & Netscape

- Show that your Mozilla and Netscape are from a trusted developer. Digitally Sign Mozilla and Legacy Netscape Object Files

- Our Code Signing Certificates for Mozilla and Netscape Objects are used to digitally sign Mozilla XPI packages for Firefox and Thunderbird and files for Netscape Objects

- Signing code is beneficial to both you and the end user. You benefit by protecting your code from tampering and building your reputation as a developer, while your end users enjoy peace of mind knowing the application they are downloading is safe and comes from a verified source

- To sign applications to distribute through the app store, or to pass through Mac OS Gatekeeper, you must use an Apple Developer ID Certificate.

Why Sign Code?

Add an essential level of trust to the application installation process. The solution is simple – Sign your code!

Unsigned Code

When end users install Mozilla or Netscape software they are warned to only install add-ons from authors that they trust. When code is not signed, it is impossible for them to know the true source and if it is trustworthy.

Signed Code

Signed Mozilla and Netscape software shows the publisher name right on the install screen so end users can easily decide if they trust the source and continue with the install.
