Here are some common issues people experience when upgrading to 3.0:
- Asking For Master Password - This appears to be an issue with manually imported certificates. A possible solution has been posted.
- Blank or Error-Filled Screen Thunderbird Screen - This can be due to the Kaspersky antispam extension which can be manually removed to fix it.
- Splash Screen Only - This means that Thunderbird is crashing on launch, usually due to an incompatible component. This will happen if you manually copy the Thunderbird 3 application files over Thunderbird 2, for example. (Always install PortableApps.com Format apps over the old version to upgrade). If you did the upgrade properly and it still fails to launch, you may have another component or non-standard add-on interfering. To fix this, delete your ThunderbirdPortable\App\thunderbird directory (after making a backup for safe keeping) and then reinstall Thunderbird Portable to the same location. That will ensure you are running a clean install of Thunderbird Portable 3 with no additional add-ons except the ones in your profile (which should be properly managed). If that fails, start Thunderbird Portable in safe mode by running
ThunderbirdPortable.exe -safe-mode from the command prompt. Then disable all extensions until you determine which is interfering.
