Hello
My suggestion is very simple and, in my opinion, very easy to implement.
The Mozilla site (www.mozilla.org) is multilingual. This is very good and it is proof of the open mind of the Mozilla Foundation and its animators.
The site is by default in English. To change the language, there is a selection menu. This is where it gets problematic. To find the selection menu, you have to browse the entire page in English, all the way to the bottom. This is an absurd waste of time and, in my opinion, a lack of respect for those who prefer to read the page in a language other than English.
Why not present the language selection menu in the same side, on the right, but at the top of the page? It would be much more easily accessible.
Thank you for your attention and congratulations on your excellent work.
