The new version 10 of Iron uses 100% of my CPU power when watching videos. I wanted to reinstall version 9 as it has been less resource intensive. So it tried to install it over my current version. However, version 10 persists.
I could de-install version 10 altogether and then carry out a clean install of version 9. However, I don't want to loose all my extensions and configurations.
Please help. Your advice is much appreciated.
