I have just installed opera browser on my n900. It works fine and, when it open windows, seems to be faster then native browser.

i would like to use it for navigating internet but it can not correctly visualize the most of pages: probably formatting problem.

Is there a way to properly load internet page with this browser?

Thanks in advance

Did you try to change the settings, for example, disabling mobile view , loading images and so on?
The settings are hidden behind the wrench symbol in the lower right corner.
