For people who prefer using their own feed readers instead of the one bundled with Opera9 here a small hint that should get this going:
The idea is quite simple: Change the protocol of all the feeds linked in a HTML page from “http” to “feed”. Then you need some way to show you the links to the feeds. Then simply bind your application to the “feed://” protocol in Opera using Preferences Â» Extended Â» Programs.
You can combine the first and the second step by using Martin Dittus' Feed bookmarklet which renders a list of all the available feeds on a webpage. The problem is, that you can’t tell Opera9 to use a specific applications for feeds, this separation is only possible by protocol. So we need to modify Martin’s Bookmarklet a little bit to output the feed links using a different protocol.
I’ve prepared this bookmarklet here:
The only difference between the two bookmarklets is this fragment:
In the original this was:
Now all you have to do is to specify whatever application you want to use for feeds using the “Programs” preferences as described above.
It seems like the whole protocol binding process it not completely consistent over different versions. I for example could only use the “feed://” binding while for other people only “feed” works. Please check out the comments in any case :)
