i'm an android phone user (A15) and i really don't like mobile website layouts, particularly when most websites fit elements to the screen aspect ratio instead of letting me pan around a more traditional 16:9 webpage. i've tried all sorts of user agent and javascript spoofing, but nothing really beats firefox's native "desktop site" toggle, but it sadly doesn't stay on across different tabs or sessions and i have to turn it on manually every time. it should be pretty simple to add this feature, and i'm sure that there's a lot of support for it too. thanks!
