Feature request. Rated 4 out of 5 stars

If this makes desktop default could you make a request mobile site option instead of desktop in the settings?

This review is for a previous version of the add-on (1.0). 

You should still be able to use the same menu item to switch between desktop and mobile pages. With this extension installed, desktop mode will be on by default, so it will be checked in the menu. You can still see the mobile version of the page by unchecking "Request Desktop Site".
