Pepperflash for Firefox?

Hi again. I greatly appreciated all of your help with my installation of Firefox 35 on my Mageia 4 laptop, however, I have found that I cannot install Adobe flash player on this browser, either from the repository or from adobe's website directly. It sounds like from what I'm reading that these later versions of firefox don't support such plugins. I've been reading here and elsewhere about a pepperflash and freshplayer workaround. I have downloaded Google Chrome per the instructions here and added the signing key. This brings me to a few questions. First I get the feeling that this is perhaps a pretty advanced project and as some of you remember, I had some trouble with the fairly simple task of installing Firefox 35 from terminal, so I don't know if this has been reduced to a fairly simple process by the community or it's still an advanced user project. Second, if you all think this is not an appropriate project, is there some way that I'm missing to run flash content in Firefox or should I just use Chrome? For YouTube I currently use the HTML5 player suggested here which works well, but often run into flash content on Facebook and a few sports and news sites. What are your suggestions? Thanks in advance.
