Hmm, why is that an issue in Wikimedia software and not a problem to solve in the Firefox software?

Not an issue with MobileFrontend. This template is defined on wiki and MobileFrontend makes no changes to it. It is of course possible the template is not compatible with MobileFrontend but that would be an issue to be fixed in the template. The problem as I see it is the "overflow:hidden;" inline style on the template parent element which disables scrolling.
There seems to be some discussion relating to this on the talk page: https://en.m.wikipedia.org/wiki/Template_talk:Wide_image, I suggest you raise that in a topic here.

Sounds like a firefox bug. overflow:hidden doesn't mean "disable scrolling on all children", which is also why it works in all the other browsers. The reason overflow:hidden is used there, is to enforce a new block formatting context.

I know what's wrong to me. Recently improves in Firefox make the usage of this HTML class restricted, so I sent a request in their talk page and the template now works! Thanks for everyone.
