I don't know if it is a problem with Liferea or with Webkit, but if I right-click on a link to a large file and choose "Save link as":
- the file chooser dialogue opens and then freezes for a very long time with 100% CPU usage. I guess this might somehow be a GTK problem, but I haven't experienced it with anything other than Liferea.
- then after I tell it where to save the file, it freezes while the file downloads.
It would be good to eliminate the freezing in both steps. In the second step this would mean downloading the file in the background, so that liferea can be used for reading feeds while the file is being downloaded.
