Very slow uploads
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?
Same thing, ~9.5MB/s
Start your Computer in safe mode with networking. Then start Firefox. Try Safe websites. Is the problem still there?
