@burnout426 that looks to be whats causing it. i've got the udl helper as i'm always converting songs on youtube to mp3.
at least its not something sinister. if my cpu fan starts going mental i just end task it.
thanks

i keep having this service worker appear on task manager.
what is it as it uses 50%+ cpu usage
i end it and a while later it starts again and my pc fan starts going mental.

any ideas?
