Not seeing any suspicious plugins or addons in the troubleshooting information you've provided, I want to ask for more information. Is this happening in Firefox's own Diagnose Firefox issues using Troubleshoot Mode?

Yes, it does. Just to be sure, I opened FF twice in safe mode. First time the second one advertised Orange phones, and the second time it advertised Lovefilm.

Maybe do a malware scan regardless? Hmm..
