On several websites, Firefox defaults to showing me mobile versions on my Desktop browser. I am on 38.0.4 (aarch64) on a MacBook Air.

Hi Stelios

I think you may be using version 138 of Firefox.

Do you have any add-ons installed in Firefox?

Do you have an example of a website where this is happening?

Hi Paul

Thanks for replying. Indeed, I am using version "138.0.4 (aarch64)".

And yes, I do have some add-ons, do you think there is one in particular that would cause this?

In my case, it was Facebook container the culprit.
