Great, thanks Carsten! Did you take care to only edit the file if necessary? Something like: grep -vq "/usr/bin/iceweasel" "$file" || sed -i "s|/usr/bin/iceweasel|/usr/bin/x-www-browser|g" "$file" Going beyond this hacky fix of mimeTypes.rdf, I'd like to know what originally created this entry and if this code still exists. And more importantly, why is about:config's "network.protocol-handler.app.http" ignored? This setting seems to be what everybody expects to be relevant, and it is directly configurable by users. But it seems to have *no* effect. Instead *only* mime information seems to be used. Either ~/.icedove/*.default/mimeTypes.rdf, or if that is missing the system's mime settings.[1] Is this behavior correct? Or should I file a new bug for that (upstream)? Greets jre [1] In a new profile there is no mimeTypes.rdf. If this file doesn't exist (or if all http related entries in there have been deleted) icedove opens links with firefox here. Then after removing /usr/share/applications/firefox-esr.desktop it uses chromium. Further strace shows that icedove checks several mime related files then, and ends up using /usr/share//mime/mime.cache. Changing the Debian alternatives system for x-www-browser to chromium has *no* effect in this case.
