For the stable distribution (lenny), these problems have been fixed in version

As indicated in the Etch release notes, security support for the Mozilla products in the oldstable distribution needed to be stopped before the end of the regular Etch security maintenance life cycle. You are strongly encouraged to upgrade to stable or switch to a still supported browser.

For the testing distribution (squeeze), these problems will be fixed soon.

For the unstable distribution (sid), these problems have been fixed in version

We recommend that you upgrade your xulrunner packages.

Fixed in:

Debian GNU/Linux 5.0 (lenny)
