As far as I know it creates midori and webkit folders in AppData. Maybe that can be taken care of somehow.
You're right. Not Portable
: saves to AppData and Temporary Internet Files. With the -p argument, it will open in private mode, but still creates the Temporary Internet folder, despite the FAQ saying that it saves nothing. It also seemed to give a lot of errors when I opened it from the command line, although that might really be nothing.
There's a lightweight web app focus of the program that I think that could be amazing down the road, but for the time being I guess its still in beta. The program calls itself portable, but this is in terms of cross-platform, not settings portability. I should have read that more carefully.
Softpedia hosts a portable version
of the program but I didn't test this as I couldn't find anything on the main site about it.
Side note: the program uses DuckDuckGo
as its default search engine, but oddly uses Google as its homepage.
I can't believe there isn't any really lightweight yet decently usable portable browser beside Opera out there...
is close, but appears to have stalled in development.
