I can't update my Add-Ins. I always get the error: unexpected installation error - 203 when installing the modules. I have found a workaround for Windows, but I have MacOS. Can you help me?

Mac OS 10.6.6 system

They are also for the Mac. If the first link which cor - el posted is information showing for Windows, in the right-hand column under where it says "help", select Mac OS X and Firefox 3.5 - 3.6
