Using Firefox 136.0 and previous vers. Some web pages are displayed in portrait mode. (or seem to be) In Firefox these pages are??? not right. If I copy and paste url to MS Edge the page displays properly even although the presentation is still in portrait mode (or seems to be). i.e. the data displayed on the page does not go out to the edges of the screen but sits in the middle in portrait mode for example see: https://www.scotlandspeople.gov.uk/ Attached images show Firefox and MS Edge screen grabs and https://en.wikipedia.org/wiki/Main_Page which displays correctly in Landscape mode (or seems to)
