2017.10.09. Have you checked whether your changes are working? Images gone in all dials, "Refresh / Refresh all" button does not work. "Very useful" update. Win7 64; FF 56.0

Hi,

This is the simples option, not always help but we encourage to try. 

- Copy and paste in address bar about:support  
- Select following http://nimb.ws/Vm5pjy 
- Rename this folder to any name and restart Firefox http://nimb.ws/awxfuW BUT don't delete it. Just rename. 

If it won't help, let us know.
