Hello, I need to deploy Firefox 3.6.11 to existing installations to upgrade them from the old version. That part is fine, the problem I have is will the silent installation update any non-compatible add-ons or extensions? I will be using SCCM for the deployement part.. I ran the installation manually on a typical machine of which it gave the option of upgrading the existing client. Thats fine but the installation then prompted that 2 currently installed add-ons were not compatible with the new version. It lets you select and then "check" for later versions of those add-ins, actually checks for updates and lets you select and install those too!! Now, how do you deploy silently with those options I`ve mentioned above??? Cant find any command line parameter that allow for that! Please Help!
