There have been lots of improvements and bug fixes in version 1.2 of the Firefox Extension, which isn't really reflected by the changelog. You'll need to update both the extension and LockCrypt (after exporting to XML).
Changes in LockCrypt Firefox Extension 1.2- Added: Exclude list.
- Added: Import and export.
- Improved detection of form field name. LockCrypt now tries to find the label, defaulting to the input name only when the label cannot be used.
- Added: Accounts can now be imported and exported between Firefox and LockCrypt.
- Fixed: If UTF8 characters were used in field names, when the database was exported to XML, the field names would fail to encode properly (Thanks Takitsim).
- Fixed: Bug with Simplfied Chinese translation.
- Fixed: Sizing bug if the language was change half way through the installation wizard.
- Updated: XStream and JGoodies Looks libraries.
