I need Flash player for browsing onion sites. How can I get this working with TOR?
You should be able to install and enable Flash within the TOR browser?
But you should also be aware that it will kill your anonymity.
How to install Flash in Tor Browser:
the links you post are to outdated articles. the instructions no longer apply to TOR Browser's file-structure.
Yes, the linked instructions are for the earlier releases of Tor Browser. As I said in my OP you might just have to enable the Flash Plugin within Tor Browser – which applies for all recent releases
So, if you are using e,g, the latest version of the Tor Browser (3.5) head over to Adobe, download and install the latest Flash Player http://get.adobe.com/flashplayer
Then within Tor Browser go into Settings > Add-ons (the orange Tor Browser button at the top left), click on plug-ins and simply enable Shockwave Flash by setting it to "Ask to Activate" or "Always Activate".
