Hello,

I can't manage (with a lot of firefox version) to subscribe to a RSS feed with akregator through firefox. The subscribe button doesn't work. What is strange is that various versions of a (dirty) solution are available for a long time on internet, which means other people have the same problem, but it still doesn't work out of the box, and I can't find a bug report concerning it ...

The problem is most RSS clients won't add a feed just by being called with it as a parameter. Akregator need -a option for exemple. Moreover, even then it doesn't always work. If akregator is already running, it won't work. Using dcop can solve the problem, but it needs a special syntax, with arguments before and after the feed adress.

I think the problem is not easy, as it would need to add a lot of options (select the binary, specify options ...), and is a mix of bug fix and feature addition. A nice (optionnal) feature could be to also handle group (asked on feed addition).

Regards,
Colin

Reproducible: Always

Steps to Reproduce:
With a fresh installation of firefox under Linux:
1.Find a web page with RSS feed (e.g. http://slashdot.org/)
2.Click on RSS icon in the adress bar
3.Choose to subscribe using your akregator (it's probably true with many other applications) and click "Subscribe Now"
Actual Results:  
Nothing happens

Expected Results:  
RSS feed added in akregator

Filling variables (in about:config):
browser.feeds.handler.default -> "client"
browser.feeds.handlers.application -> "dcop"
browser.feeds.handlers.application.afterArgs -> "] Imported"
browser.feeds.handlers.application.args-> "akregator AkregatorIface addFeedsToGroup ["

and using the following patch, it works:
