Is it possible to add automatically a feed in rssowl when I click on rss/xml link on Internet Explorer ?
This is currently only possible when you use the internal browser inside RSSOwl.
Sorry, I meant to say, this is currently only possible for links that use the format "feed://www.url.com"
Supporting something like that will be investigated for the future, but can be tricky. Especially when you use the Internet Explorer outside RSSOwl.
