Firefox is brutally slow on speedtest.net
When using Firefox, my network speeds are brutally slow (~35 Mbps), while Edge is (~300 Mbps, which is my service speed). I am hardwired through my router, but it is the same wired or wireless.
I have literally tried every single step through Firefox's troubleshooting and have even completed what I thought to be an entire uninstall and deletion of every single Firefox file on my laptop. Upon uninstall and deleting of EVERYTHING, I reinstalled only to be greeted with "Hey, it looks like you reinstalled Firefox, want to refresh everything?". I did (another) refresh and still, same speeds.
Is there a way to 100% remove Firefox and reinstall? I want my laptop/Firefox to treat each other as never have met, in hopes that I can install and get the speeds I should be getting.
Interesting note, Firefox for Android gets ~300 Mbps no problem on my phone.
Thanks in advance!

You can create a new profile to test if your current profile is causing the problem.
See "Creating a profile":
If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
Did you make sure that security software isn't causing this issue?
It is possible that (anti-virus) security software is causing the problem. Try to disable security software temporarily to see if that makes a difference.
