When browsing on my iMac 27" Retina full width screen views webites as if it's an iPhone. Which is very annoyning fills the window as if it was mobile phone. Sometimes when doing a supermarket shop it goes big when you move the mouse sideways! I have a WordPress website using a Divi theme and this is displaying incorrectly. It's fine in Safari! https://www.reevesdesign.co.uk/ This has only happened since the latest update Firefox 89.0 Weird I have just cleared cache and it views OK. Still got that annoying big screen when shopping, that you can't get out of. Anyone else getting these problems on iMac please?
