When is working
If i start my thunderbird at my flash disk and i run from host. This profile same, host put profile from my portable. If i edit ini files my thunderbird crashed.
Check localization links
The link to the English test homepage points to the non-test homepage for Firefox:
https://portableapps.com/apps/internet/thunderbird_portable/test/localiz...
not sure this is working after upgrading..
I installed 3.0rc1 into the same folder as my portable thunderbird 2 (latest version from this site), after launching it runs the process "portable thunderbird.exe", then "thunderbird.exe" and after a few seconds both quit without displaying anything.
Warning: this version appears to be buggy.
In the meantime Mozilla has released RC2. According to the changelog they've fixed a few very serious bugs.
Probably it is better not to use this RC1.
