There weren't any questions. I replied to the OP about how to install the flash plugin. If it is manually installed, then, yes, one would have to keep track of updates and download the new version.
The frequency of updates to both flash and the browser is getting out of hand. If those autoupdaters are left running, then the computer is doing nothing but downloading new stuff every other day.
This here site is maintaining direct downloads of the plugin without an installer (and all the service crap that comes with it):

I just went there and copied Flash 18.104.22.168. There is a new ad on the Flash context menu now about some "games on Adobe Playpanel". Back to Flash 11.4 which is 9 MB compared to this one which is 16 MB.
