FIrefox causing DNS leaks!

I AM using VPN and I found Firefox is leaking DNS, as it doesn't happen in another browser. I read it is caused by automatic updates: https://www.reddit.com/r/privacy/comments/2e20ni/firefox_dns_leak/ I tried to disable automatic updates by flipping this value: "app.update.auto" in about:config to false. But it did not help.

Can you please help me to fix this, I don't know what it's causing it...

That Reddit thread is from seven years ago. Did you verify that you still see this ?

You appear to be using Firefox from the Ubuntu repositories, so updating is controlled by Ubuntu software management.

First thank you for the answer!

Yeah, I AM seeing this for awhile! I was unable to solve this with my VPN provider.

I have no idea why this is happening, I didn't even know that browser can override systems dns.

Correct I AM on Ubuntu, what Firefox concerns: I AM on latest 91.0.2 and I tried reinstalling Firefox, also happens even with no addons!
