Comment 101 for bug 14911

The following was the case with Dapper, which also had the Firefox crash problem:

After seeing the problem, post-performance of 'apt-get dist-upgrade'... I saved all the downloads, recovered the previous day's backup and commenced, on a hunch, to manually upgrade Firefox, rather than upgrading the whole enchalada at once (as I usually do, with 'apt-get dist-upgrade'). Instead, I performed 'apt-get install firefox' after the downloads were all completed.

The result was that the 'mozilla-firefox' package was removed ...and with that, the flash plugin/Firefox bug was also removed. Subsequent 'apt-get dist-upgrade' then upgraded the remaining packages --minus mozilla-firefox, of course.
