Icedove-UXP becomes stable replaces Icedove

After several weeks of testing, we are happy to announce the first stable release of Icedove-UXP. Unlike previous versions of Icedove, this is a completely new application built against the UXP toolkit.

Some of the new application features:

  • New internal web engine with regular security updates, courtesy UXP.
  • More complete and thorough Icedove branding than any previous version.
  • Supports XUL Addons (not WebExt for privacy reasons).
  • Hardened now excludes access to /proc for additional security.
  • Several longstanding javascript bugs were fixed with backports that were not included in Thunderbird 52.

Note: All addons are incompatible with this version of Icedove but can be backported, please make your requests on our issue tracker.
