thank you Chantelle, I did what you suggest before opening this thread, it does not work ...
I installed the latest version of mac-catalina (10.15.17)yesterday but I also installed adblock one and I suspect this stuff is causing this, I have to find a way to uninstall this properly, if you have any idea thank you in advance.

edit:
so I find the guilty !
it is the adblock which did that, you just have to deactivate adblock which works in "submarine" and everything return ok. Bye
