Operating system: Linux Mint Package manager: APT

We are here talking about updating Firefox, which comes pre-installed with the OS.

While other packages go up to 13 MB/s, Firefox downloads remain at a maximum of 500 kB.

Get:1 http://packages.linuxmint.com virginia/upstream amd64 firefox amd64 124.0.2+linuxmint1+virginia [74.3 MB]

Should I switch to different source?
