Log my download speeds when using Firefox

Is there a way to log my download speeds when using Firefox?

I know about speedtest-cli.

I would like a log of my download speeds when I am using Firefox. Firefox shows the download speed as a file is downloaded but does not keep a log of it.

Have a look at vnstat, to see if that meets your needs:

Example from that page (reproduced):

$ vnstat -5

 eth0  /  5 minute

         time        rx      |     tx      |    total    |   avg. rate
