I'll try those. Right now, I do not have (graphical) access to the machine where I have built qupzilla. From memory, it may happen that the first visited site may last longer than 5 sec, but after a few link followings, pages first load, then disappear with the message: "cannot load page, try to free close tabs to free memory, and try to reload". According to top, a lot of memory is free. When I hit the "reload" button, the page appears for a few seconds, and then dissappears again. I have no time to look at this tonight. I'll try to do something tomorrow, but I may have a lot of other things to do, so not sure.
