ReferenceError: BrowserToolboxCustomizeDone is not defined
I am using Firefox for many years and I believe that it is the best browser in the market place, however I recently receive this message "ReferenceError: BrowserToolboxCustomizeDone is not defined" when I start Firefox for the first time in the morning. Could somebody help me to resolve this problem?

Its your addon issue, check your addons are uptodate and try in safemode too
Start Firefox in Safe Mode to Troubleshoot the issue and to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
