Comment 19 for bug 526290

Installing thunderbird-gnome-support did help in the way that firefox is now proposed when clicking on a http: or https: link, but why tb even asking, when I have set my preferences in the 'preferred applications'?

Now tb is offering the right programs for viewing pdf, gif, tiff, but it has no idea about png files. all it does is to offer me to save it (or cancel).

I have other problems with tb, it has become too smart and too eager to do prefetch and store everything, so now on my netbook, with a slow SSD, I am bogged down by all the writing of tb to the hard disk. The tb 2.x was much easier to use. Maybe it is time to take a look at alternatives.
