Hi 
Yes, it should. Sadly what 'should' be is often different from what is
although i've rarely had problems with LibreOffice. Midori on Ubuntu 12.04
had no problem with the download.
Hmm, actually the page seemed to think i was on a Mac so it gave me a .dmg
to download but that worked. Then i clicked on the "change system" and the
.deb downloaded. Midori has this weird thing where it gives a pop-up
asking if i want to open or save or a couple of other options. maybe your
web-browser is doing something like that and then just hiding the pop-up?
Doesn't sound likely to me as i've only had that sort of thing in Windows
but it might be possible.

Tom
