I'm not sure this is a bug because Firebird itself seems to work perfectly normally without this file. However, it would seem that other extensions might make use of files that the base product does not. Shouldn't all the components in the ZIP version be installed by the installer version? Reproducible: Always Steps to Reproduce: 1. 2. 3.

What is the component for spellchecker? I'm just curious, because I'd prefer composer.xpt be removed from the zip builds, too.

I don't see it on http://lxr.mozilla.org/mozilla/source/browser/installer/windows/packages-static

It is the responsibility of the extension to include all necessary parts. http://forums.mozillazine.org/viewtopic.php?t=34799
