The URL you quote is just a link to the information page on WMS servers operated by IGN. You need a URL to a specific server to be able to use a given WMS server as a data source.

You also need an access key. For example, the sample URLs on the site, such as

you must replace CLEF (the key) with your personal key. That's covered in the page in the commentary "Le paramètre CLEF doit être remplacé par votre clé personnelle ou par celle définie dans une URL d'accès libre aux services web." ("The KEY parameter must be replaced by your personal key or by the one defined in an open access URL to web services.")

Presumably, if you're connecting to WMS using QGIS you have a personal key or a URL that is an "open access" URL to web services. You could use either one in Release 9. There's probably some info on the IGN site somewhere on how to get your personal CLEF.

I tried:

... and it worked fine.

I also tried (adding the s in https...)

... and that worked fine as well. I'm using build, the latest build.

I'm glad it works for you!

it may be a problem with M8 that I currently use.

Can you tell me how you do in manifold 9 which I also have but don't use?

I see that the import works differently in M9

Here's a topic that's a good start: Web Servers. There are other topics with specific examples of using WMS servers, like Example: Connect to a WMS Server for National Map Layers

You can download the free Viewer and try all that out in Viewer.

It is likely that you have a personal key or a "open access" URL to web services if you are using QGIS to connect to WMS. Version 9 allows you to use either one. How to obtain your own CLEF should be covered somewhere on the IGN website.
