Version: 1.2.2 (using KDE KDE 3.5.2) Installed from: Debian testing/unstable Packages OS: Linux Firefox 2.0 will have an option to configure your favorite feed reader (which is of cource aKregator ;-) ). Clicking the feed icon then tries to add the selected feed to the configured reader. To do this Firefox simply calls akregator <url> instead of akregator --addfeed <url> It would be nice if aKregator accepted the command line syntax Firefox 2.0 tries to use. To try this out download Firefox 2.0 Alpha2 from http://download.mozilla.org/?product=bonecho-alpha2&os=linux&lang=en-US and configure the option in the dialog "Edit|Preferences|General|Choose Feed Reader...".
Another option would be to write a quick little shell script called addFeed.sh which contains ---- #!/bin/sh akregator --addfeed "$@" ---- and then tell Firefox to call that.
I fixed this already last summer..
