I've installed Midori to work in an Elementary mockup. Midori works just fine, but, on a few domains, it opens mobile websites instead of the regular pages. A of now, this happens with gmail.com, facebook.com, paginegialle.it, and others; yet other websites which do have a mobile version, as gazzetta.it, show the regular version. I couldn't find a solution through settings and I didn't find any mention of this problem on forums or else, so any help would be greatly appreciated.
Since i have not used midori i cannot be sure, but from reviews, it is possible to change the user agent in midori. switch the user agent in Edit - preferencces -network to something like firefox and you issue may be fixed.
I use midori as my default browser, and after that I set "identify as Safari" and all problems were fixed.
You can tell Midori to "Identify as iPhone." Perhaps this is set. Check in Preferences > Network tab > Identify as drop-down menu.
