It would be excellent if there were some way to disable flash animations in Mozilla. A run-time option would be ideal, but a per-user option would suffice.
I would suggest you uninstall flash from /usr/lib/mozilla/plugins and have users install it in their user plugins directory. I don't have the exact information off the top of my head, but you can look it up. Overall the best way IMHO is to not install it at all and then remove the null plugin so it doesn't bug you on pages that want to use flash.
Shaver said on #linux that to remove the files is the only way. Unfortunately, this does not help if I want to keep Netscape 4 working as before.
My advice would to make an RFE at bugzilla.mozilla.org to have an option to unload plugins on run
Exactly! Mozilla is not produced by Red hat, but barely supported as it comes. The requested feature is beyond Red hat's capabilities. On a side note, there is no flash player in the next release anyway.
If this gets fixed upstream, we'll pick it up.
