Firefox is very slow to upload files. Testing a large file to Google Drive I get around 9.5 MB/s, while using Chrome I get 18-19 MB/s. ( I have 310 Mbit upload which would cap around 37-38 MB/s)

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options)
key, and then starting Firefox. A small dialog should appear. Click Start In Safe Mode (not Refresh).

Is the problem still there?

Start your Computer in safe mode with networking. Then start Firefox. Try Safe websites. Is the problem still there?
