Start Firefox in Safe Mode to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe Mode start window.

You can check for problems with current Flash plugin versions and try these:

  • disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
  • disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
  • disable hardware acceleration in the Flash plugin

While the posted solution to my sync issue could very well correct my problem, the poster presumes I am computer literate, which I am not. lol could the solution provider please explain the solution as is it were being given to a 6 year old? Although most 6 year old's are possibly more computer literate than I. lol Thank you for your time.

I will be checking back for any response.

You can use one of these to start Firefox in Safe Mode:

  • Help > Restart with Add-ons Disabled
  • On Windows, hold down the Shift key while starting Firefox with a double-click on the Firefox desktop shortcut

Please report if that has any positive effect.
