Your header shows that you're now running: X-Newsreader: Forte Agent 6.00/32.1186 which should be able to pickup the URL's between the brackets. I can't imagine that Wine is causing any problems. I'll try it after I restore my Ubuntu 10.04LTS laptop from backups. (Don't ask, I goofed).
Firefox 3.6 is seriously neanderthal. The current Firefox release is
18.x. Methinks an update might be a good idea. Also, there's no need to run the Windoze version of Firefox under Wine since there are native Linux versions available, unless you need Flash or some other Windoze exclusive plug-in.I don't like to use tinyURL unless the original URL is absurdly long, such as a Google maps or Google Earth URL. There's too big a chance that the target for a shortened URL is a hijacked web site full of evilware.
I don't see why a YouTube link would be any different from any other link, unless the URL has Unix specific special symbols in it, such as the "|" symbol, which might break passing data between programs in a pipe if the shell got in between and tried to interpret it. What part of the YouTube URL did it fail to pass?
