hello,

Since my last package updates, Firefox has been replaced by Firefox ESR.
My prob:
In Firefox ESR I cannot access some websites (most of them) (ex: google, duckduckgo,...). Few are accessible like all Kali and yahoo.
No error message: after opening a new tab, and entered the website (ex: www.google.com) I can see written in the title of the new tab "Connecting...", and then it stops and nothing happen.

Few info:

Gnome version 3.28
