Issue to access websites from Firefox ESR

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Since my last package updates, Firefox has been replaced by Firefox ESR.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

Any Ideas guys ?

Did you try adding the https:// prefix e.g. https://www.google.com ?

Hi @Padgett, yes I tried. It’s not working neither when trying with https.

Did you tried http://www.bing.com If sites other than google loads up then it is your DNS problem. Change your DNS in your wifi network.

I got the same problem too.. after i upgraded from Kali 2017 to Kali 2018 I cant access to google.com, youtube.com and some other website..
ping responded but cant access to the web cant google search engine also cant used after i simply type anything to search..

Linux Se7en 4.6.0-kali1-amd64 #1 SMP Debian 4.6.4-1kali1 (2016-07-21) x86_64 GNU/Linux

That is very old kernel. Current is 4.14. You might want to reinstall.

Linux Kali 4.6.0-kali1-amd64 #1 SMP Debian 4.6.4-1kali1 (2016-07-21) x86_64 GNU/Linux

I run the above version also and am having the same problem. Has anyone come up with a definite solution for this? Or is doing a full reinstall using a later version of Kali the only solution?

Edit: I bit the bullet, downloaded the latest ISO and decided to do a full rebuild. Firefox-esr appears to be working fine now - so thank you.
