Comment 27 for bug 1284479

Much has changed regarding the Flash plugin and its support by Adobe and Canonical since this bug was reported. Things are better and simpler. This bug is unlikely to still be occurring, and if it were it certainly wouldn't warrant a Critical status.

The Flash plugin can be installed and kept up-to-date via the flashplugin-installer package in the multiverse repository (NPAPI version) or via the adobe-flashplugin package in Canonical's partner repository (NPAPI and PPAPI versions, recommended). It is currently version 25.0.

I've set this old bug to expire. Please report problems here, or in another bug report, whichever is more appropriate.
