I'm running Mozilla Firefox for Ubuntu 74.0

For some reason it is running really, really slow. Loading a page like Youtube takes more than 10 seconds. At first I thought it was an internet problem, however speed tests shows 60-70Mbps download speed. I tried using Chrome and it is considerable faster tan Firefox. (For example, Chrome takes 2-3 seconds loading Youtube). I tried restarting Firefox, disabling all extensions, but it didn't help.

As last choice I decided to remove Firefox, then I deleted the /.Mozilla folder. I rebooted my pc and then installed a new fresh Firefox. It didn't help at all. I don't have any idea of why is this happening, I don't use any proxy or firewall and I'm not used to Chrome.

Thanks for your help in advice.

If you suspect Extensions might be causing a problem, be sure to: Disable your extensions, then, Restart Firefox and try again.

The problem was the DNS.

I do not know why, but I changed my router DNS from 0.0.0.0 to 8.8.8.8 and firefox is now fast as chrome.

Thanks for your help.
