podcast subscription links + firefox -> sent to MM

[AltairJr]

I know this isn't exactly a MM issue, but i'm trying to get firefox to open podcast subscription links and 'send' them to MM. I'm used to just copying and pasting the link or using the non-itunes rss feed link - but some podcasts use the address that starts with itpc://{subscription link} and MM can use those just fine; my problem is some podcasts only have a javascript (or something like that) link that doesn't give me address to copy

I know I might have muddled what I was trying to explain but if anyone could make enough sense to help me that would be great.

MM accepts podcast links posted from firefox to subscribe.
Maybe the best would be if you bring in a concrete example which doesn't work for you.
