I'm pretty sure that once I was able to
- press f,
- then enter a number,
- finally hit Enter,
and the link opened in the browser (I use qutebrowser).
This doesn't seem to work anymore, in that following the procedure above, step 3. doesn't trigger any reaction in the browser, just like I've done nothing at all.
Unfortunately, I don't know since when, so I'd like some help in troubleshooting it.
On the other hand, in-document links are followed just fine, so I think that zathura simply doesn't know (anymore) what application to forward those links to.
Fwiw, I use i3 as window manager, no desktop manager.
