error console
Why is an error console appearing every time a new window of FF opens?
It usually contains a lot of "errors", yet everything is working well.
It is annoying to have to continually close it.

Do you have any mouse gesture extensions (Tools > Add-ons > Extensions) ?
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.
