proxychains does not work with browsers (chromium, firefox) but work with curl

Question

I am trying to configure proxychains4 to run browser.

sudo apt update && sudo apt install proxychains4 tor - to install packages (also tried to make it from repo)

sudo nano /etc/proxychains4.conf - to open configuration. Strict, dynamic, round_robin modes were tryed sequentially. At the end of the file socks5 proxy was added in format socks5 176.103.xx.xx 29xxx username password right after I removed default socks4 proxy.

sudo systemctl start tor.service - to start tor

sudo systemctl status tor.service - to check tor is running

~$ sudo systemctl status tor.service
● tor.service - Anonymizing overlay network for TCP (multi-instance-master)

proxychains4 curl ifconfig.co/country - to check if proxychains works. I expect to see Ukraine, because proxy server placed in Kharkiv.

~$ proxychains4 curl ifconfig.co/country

Ukraine

Everything ok, for a while.

Firefox

proxychains4 firefox dnsleaktest.com to run firefox. Problems start here

~$ proxychains4 -f /etc/proxychains4.conf firefox dnsleaktest.com

Browser runs successfully. But it shows my real ip address in Kazakhstan. Surfing on browser does not generate new logs in console.

Running chrome is also successfull, but ip is my real one. But the logs are different from firefox ones.
