I already have this one mostly figured out. 12.1 KDE Firefox 9. Flash worked in chromium but not firefox. Flash works when I changed .mozilla to a different name according to a suggestion in another thread. I’m not sure why that was suggested and I do not know what I need to do to get flash working with my old profile.
Ended up renaming .mozilla. Then running firefox so that it creates a new .mozilla and moving files one by one into the new .mozilla.
