What I wanted to say is that it's not faster than others Qt web browser under OS4 like QtWeb or ISB. And regarding the optimisation, only Alfkill could say...
QupZilla is not really nicer than the others qtbrowsers but if you want to try :
@zzd10h If it works well, think about sending screenshots and promote it at the Qupzilla website http://www.qupzilla.com/. It is good to have there the AmigaOS boingball logo and promote further our beloved OS.
QupZilla might not be better for some of you guys, but I do like it better than some other Qt browsers. It has more features (esp. in the newest versions), it's very cross-platform (on the Download page you can see all the platforms supported) and the interface is just nice to use. And it supports extensions (native ones right now, but before Summer 2016 it will also start to support Chrome extensions). I love using it on my Linux and Haiku machine and been using it for a few years now :) But I'm more on my Amiga these days. And while Odyssey is near-perfect (and better integrated, of course!), sometimes a page doesn't work as well as in, say, QupZilla or Timberwolf (but Timberwolf is not useable on my AmigaOne 500). So it would be nice to have my other favorite web browser QupZilla (Odyssey and QupZilla are my two favorites!) available for use on AOS4 :) The newest version, if possible, of course. So if anyone is up for porting the newest version and makes sure that at least browsing, the built-in AdBlock and themes work, I'll gladly donate a nice amount of money to that person.
I'm kind of a noobie when it comes to AmigaOS. I'm using Linux since 2008 and since Summer of 2013, I got my first Amiga ever: AmigaOne 500. I recently upgraded it with a RadeonHD card. I've really fallen in love with AmigaOS 4.x
