Mobile versions loading on Mac desktop

I have the most recent Firefox on my Mac desktop. For the past few weeks, I have had an intermittent issue with Google search, YouTube, Facebook, and my Yahoo inbox being loaded as mobile versions instead of desktop versions; this is the case both in regular and private browsing. Currently, I'm getting ONLY the mobile versions for these websites. Any help would be greatly appreciated!

Are you using bookmarks to load those pages? If so, perhaps those are mobile bookmarks that were originally saved in Firefox for iOS? Check the "Location" line in bookmark properties for each of those bookmarks.

I don't have Firefox for iOS, and this issue exists whether I use a bookmark or type the address directly into the browser; the "m" is automatically inserted into the URL as the page is loading.

Anyone? I'm about to lose access to Facebook messenger because the mobile version is only going to allow access through the app!

You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").

Using "Forget About This Site" will remove all data stored in Firefox from this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website then data from that website will be saved once again.

Interesting idea, but unfortunately it didn't change anything; all I got was mobile versions of these websites logged out of my accounts.

You posted with Safari or Google Chrome, so we can't check the user agent.

What are the screen dimensions reported in case that makes a difference?

I'm posting on Safari, since nothing is working in Firefox. I don't know which information you wanted from that website, but I think this is everything:

JavaScript screen.width x screen.height = 1920 x 1080 window.devicePixelRatio = 1 device pixels per CSS pixel True screen.width x screen.height = 1920 x 1080

JavaScript window.innerWidth x window.innerHeight = 1661 x 966 window.devicePixelRatio = 1 device pixels per CSS pixel True window.innerWidth x window.innerHeight = 1661 x 966
