Try reinstalling the previous version of Flash - 10.1 r 102 and get rid of that 10.2 r152 version.

Download Flash Player 10.1 (Non-IE Browsers)

Adobe flash player won't let me install a later version. says there's a new version and does not give option to install old versions. I spoke with adobe and they said Foxfire has not yet updated their browser to work with their new version. The 10.152.32 works fine in internet explorer.

I gave you a link where you can get the older version version of Flash.

Maybe Adobe did a better job with the IE ActiveX version of Flash than they did with the Plugin version?? IE and Firefox use different versions of Flash, so a direct comparison is fallacious.

That's what I'm saying, I went to the link for the older version and when I get ready to install, I get a prompt saying a newer version is available than the one I'm trying to install. It gives a link for the new version, but not a choice to go ahead and install the older version. I'm not very computer savy. I assume Firefox would want to get their version of Flash working with the new version of Flash. I'm noticing more and more videos that won't play.
