2.0.0.24?

Please make the 2.0.0.24 version portable, too. I read that the 2.0.0.25 is being worked on, too.

I find 3.x Thunderbird clumsy and slow -- sort of, the programmers let loose without proper supervision and too much jolt-cola/candy-bars. I have reverted on my desktop/notebook systems, and I am looking for alternative e-mail software that manages multiple accounts. In the meantime, I really would prefer to keep my 2.x version of T-bird. Could at least one such option be available?

A build error occurred in the last Thunderbird builds causing the non-localized all-l10n.js to be included instead of the localized ones. This will be fixed shortly.

WORKAROUND 1: Until then, you can copy an all-l10n.js from your local Thunderbird install from C:\Program Files\Mozilla Thunderbird\defaults\pref to your portable version in X:\ThunderbirdPortable\App\thunderbird\defaults\pref.

WORKAROUND 2: If you don't have access to a local install, download the standard Thunderbird installer from mozilla.com for your version of Thunderbird in your preferred language and open it in 7-Zip Portable. Browse to \localized\defaults\pref\ within the installer and extract the all-l10n.js file and copy it to X:\ThunderbirdPortable\App\thunderbird\defaults\pref.

WORKAROUND 3: You can even just edit the file yourself (using something like Notepad++ Portable) and change it to your preferred language. For dutch, for example, delete both uncommented lines and add the line: pref("general.useragent.locale", "nl");

This is the only file affected by the build error. It should not affect Thunderbird itself, just extensions (which are used much more rarely in TB than in FF).
