Comment by tamplinjohn: Did you build with make BROWSER=ff35, and then install the generated oophm-xpcom-ff35-xpi? What shows up under Tools/Add-ons? If you run firefox from the command line (with no other instances running, or else using -no-remote and a different profile), what messages do you see on stdout/err?
