Is there a solution to high CPU usage in Windows 10 when streaming or downloading audio files via Firefox
Trying to play or download audio files via Firefox in Windows 10 results in stutter or crashing. This is because CPU usage jumps to 70% or above. The culprit appears to be 'System and compressed memory', which accounts for all of this - it kicks in despite having 8GB of RAM!
It's probably another Microsoft mess but who knows.
Thanks to anyone who can take this up - I'm a silver surfer and these modern computers are beyond me (my first computer was a DEC PDP 11, I'm that old)

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?

Thank you for your suggestion (and the instructions) but no, it makes no difference.
I've called the big guys to help you. Good luck.
Start your Computer in safe mode with networking. Then start Firefox. Try Safe websites. Is the problem still there?
I tried this but safe mode with networking cuts out Windows Audio Services, so no sound.
Restarting in normal mode after this reduced the CPU usage and allowed the audio download. So it seems that I'll have to restart each time I try this again.
Many thanks for your help and patience.
