Hi all thanks for your responses,

Opera mini 8 is blazing fast, I might use it for browsing news sites from now on, rather than outdated opera mobile. I don't like that it reroutes your traffic to (in my case) an opera server in Iceland, not usable IMO for logins. I remember thinking the same back when still using a Nokia N8.

Fennec 17 on a fresh and updated CSSU thumb backup copied temporarily via backupmenu is also fast and loads the site, however we cannot choose properly the date and location into the Airbnb homepage.

VNC I could try and set that up but for quick and dirty lifesaving I prefer not to have a setup that is remote and non-touch friendly. I would not use the server for anything else at the moment.

Jellyroll has found the solution with iceweasel 38, it has proved to worked fully on your device, I have to try that out for myself now.

Full javascript loading is possible on Nokia N900 after all, in 2015.
Thanks so much
