I think the 'Request Desktop Site' menuitem won't work, because the default user agent string does not contain the word 'mobile', and by default, it contains a string for non-free software.

I know, it's supposed to be the most common string to reduce UA fingerprinting, but eventually, it will be out of date and relatively easy to distinguish.

To follow thread with right subject:

I see a "Request Desktop Site" option at main menu, but it doesn't seem
to have effect.
User Agent may need to only add or remove "Mobile" word when user uses
"Request Desktop Site" option. And this option could be enabled by default.
