New In This Release

In addition to the updates (included Thunderbird updated to (release notes), launcher updated to improve cleanup of empty profile/profiles directories and unreadmail keys that were previously deleted and installer now preserves any installed GPG binaries) this revision fixes an issue where non-English packages would display multilingual extensions in English. The English build has just had a version update to keep it consistent with the other builds. Users of the English package do not need to upgrade from

GPG 1.4.9

GPG, in conjunction with the Enigmail extension, allows you to sign and encrypt your email. Learn more about GPG and Mozilla Thunderbird, Portable Edition. Installer / Format

It supports upgrades from Thunderbird Portable 1.5 & 2.0 by installing right over an existing copy, preserving all your email and settings. And it's in Format, so it automatically works with the Suite including the Menu and Backup Utility.

.. instead of having the Portable Apps menu with different package configurations, how about having some useful add-on's such as thunderbrowse etc.

You can't distribute Thunderbird with extensions preloaded. And the end user can just as easily add them to the portable version as they can to the local version.

Sometimes, the impossible can become possible, if you're awesome!

Is this to do with GPL or would all those other devs need to be onboard, I'm supposing the former.

It's to do with licensing. We have an agreement with Mozilla making it legal for us to package our portable versions and use their trademarks. But it doesn't allow for extensions (which makes sense as they want a consistent end user experience).

Plus, it goes against one of our goals which is to keep the portable versions close to the local versions mainly only making changes that enhance portability. Rarely we'll venture further (see CoolPlayer) in which case we made it clear with a slight name change and making it clear on the app homepage.

Sometimes, the impossible can become possible, if you're awesome!

the License agreement (John T. Haller) has with Mozilla. And the normal version doesn't have any extensions preloaded, so why should we?

The Mozilla community just started to offer packages of selected extensions, many more will follow:

If you want to participate, just suggest user-generated extension packs, for example like a shopping basket in the current AMO ( user interface.
Contact AMO through the Wiki / IRC
or on a blog, i.e.

Or start a community project on

... the fix works fine.
Extensions (including enigmail) are localised again and GPG is alive Wink

Paid for Software more or less?
What You need is OSS!

In the releases, the unreadmail keys are still being left behind when they didn't exist at the start.

This still happening for anyone else?

the portugese lang pack is available here.

The offline features in this release are severely broken. How do we report bugs? Also, how do we downgrade to an earlier version? The download page only lists the current version, without any links to the previous versions.
