I have had a lot of issues with Windows 10, mainly revolving around performance and compatibility of certain programs. With Google recent announcement that SilverLight will no longer be supported, I decided to make the move to Firefox (again).
But I found the FF had performance issues too, revolving around typing lags in text fields. This is what I did to fix it.
Right-click on the shortcut and choose Troubleshoot Compatibility. Normally, this is something that I would rate up there with Windows Help as being effective. But in this case, it completely fixed my issue!
Here is the generated log from the process
