How do I Install Adobe Flash Successfully?

[Cosmic_Torment]

I have Vista and Firefox.  I've downloaded v. 11.4 several times and each one is a bad installation.  Same thing with the plug-in.  I have to keep it uninstalled or else I can't upload work files.  But I constantly get prompted to install the damn thing until finally the sw says, nope you're not doing another thing until you download me.  I get messages like host debugger, as if I know what to do.  I get messages like Flash Player has stopped working, and this happens right after it has been installed.  It's a vicious circle.  I'm downloading from the Adobe Flash site.  Right now it's uninstalled, so I can upload work files.  Can someone in the community advise me what to do next?  Thanks for your help.

Can you provide a screenshot of such a message?  It's not something I have seen before.

And what do you mean by "upload work files"; is that something that requires Flash?

I have to recreate the debugger popup message.  I upload work files to an online job site for my clients. If Flash is installed I can't upload.  If Flash is uninstalled I can upload.  I haven't tried safe mode yet.

Do you have the standard Flash Player installed, or the content debugger?

Regarding Safe Mode -> Help | Restart with add-ons disabled.

I have Flash Player installed, not the content debugger.  But I get popups asking about content debugger and the host (these are options, you're supposed to select), but the popup is non-responsive and is hard to get rid of.  I have to recreate the debugger popup.  Which means I'll have to install Flash which messes with my online tasks.  I'll have to wait until the end of the week to do this, it takes up so much of my time.  I've taken a ss of your last post for safe mode.  I'll check in when I can get these issues researched.  Thanks, Pat.

One more question: if you restart Firefox in Safe Mode, does that also happen?
