I already upgraded my home's internet speed up to 1Gb. It included a router's change. The fact i, when i do a speed test on Firefox, it does reach only 600 Mb download speed and 100 upload. If i do the same speed test with another browser, i get 900 MB download and 100 Mb upload. So , how do i configure Firefox in order to get same values than Edge and Chrome browsers? I understand it might has to be with some parameters in about:config . Could you give me some light on this? Thanks

That link does not solve or even help solve the issue. I am in the exact same boat as OP. I have 1 gbps up and down and can get the download no problem. When it comes to the upload speed it caps out at about 125mbps for me. I can swap over to Edge browser and get the full 1gbps up and down. This must be an integrated setting within Firefox that caps out the upload speed. I think OP and I, as well as others who may be having this issue, would really prefer to be able to get our full speed.

So I kept looking into this and figured I would try just uninstalling and then reinstalling Firefox.... And it worked. Signed in and synced with the same account and it was giving me full speeds like it should have after... I don't really know why that worked, but it did. Give that a shot and see if it helps.

Not sure if it's important, but on the download page for Firefox I selected "Advanced install options & other platforms" underneath the main download button and selected the Windows 64-bit version. Once the 64-bit version was installed there were zero issues.
