Firefox Portable x64

Hello,

I am on the search for a 64 bit solution for Firefox. The reason being...

It's for use in an enterprise environment, we currently have Windows PE x86 configured with tools such as Firefox portable, 7-zip, data encryption / decryption tools, the windows recovery environment and MS DaRT.

Usually we could have made due with the x86 WinPE environment only, but our primary OS in the company is Windows 7 x64, so almost every machine has that. the windows recovery environment and DaRT x86 will not work on a 64 bit operating system, so a new 64 bit WinPE environment must be made that has these 64 bit components. It also means putting 64 bit only applications in it because WinPE x64 cannot run 32 bit applications at all.

Firefox from Windows PE isn't just used for simply googling, we use it so techs can get to internal web pages in order to obtain information needed for the machine they're working on, in regards to its encryption state and key, and allows them to download the necessary encryption files on the spot. 32 bit Firefox won't run in WinPE x64, nor does any other 32 bit application. I am in need of a 64 bit solution if this is possible.

Thanks!
