Unless another user on here is from your same location and ISP no one can tell why what your bandwidth is doing and how the Browser is affect by the internet.

Well my bandwidth is only limited on the Firefox browser. As stated above when I run a speedtest on Edge or Opera I get my full speed but not on Firefox is there something inside Firefox that prevents it from getting full download speeds?

Did you try to run it in Private Mode/Incognito browser to see what happens.

I did run it in Private mode with the same results. Maybe there is something limited by Firefox when it comes to web browser speed test. Not sure.

Here are my results. With these speeds... Is this really an issue?  ;-/

It sure is. Why would Firefox limit download speeds? So if I'm not getting correct info from a speedtest then I'm not actually getting full speed when downloading something via their web browser.
