I currently have Windows 7 Professional X64 SP1 and my brother has xp sp3 pro and both of us have been experiencing with firefox latest version a nasty bug or 2! You see on my end Once I leave firefox in memory for long enough it tends to cause 2 plugin-container.exes to load into memory as well which also cause yet another program to have problems as well! On my brother's computer he has told me recently that he has uninstalled completly and reinstalled and just so happens it still will come up under the check for updates as apply downloaded something or other! What I am trying to say is on my brother's computer it thinks that there needs to be another version known as firefox version 3.6.15 to be installed when really it does not need to be installed because it is already installed and etc. The question being is What would be a possible resolution to both of our current problems and in other words is there something on our that we need to do to fix it or does there need to be a bug fix release or whatever! Just speculating and Thanks for listening!!!!.
