Comment 6 for bug 74738

The packages in the backports repository are provided as a convenience to users who wish to experiment with newer versions of software without upgrading their entire systems. They do not receive security updates, nor rigorous QA, and are considered unofficial for support purposes.

The official Firefox and Flash packages do not have this problem, so this crash can easily be avoided by using the packages provided.

If this bug can be reproduced on a Feisty system, that would be useful to know, although we probably cannot do more than to report the bug to Adobe. We only make it easy to install the Flash plugin; we cannot analyze its bugs because it is not an open source program.
