I have portable SP6 and portable Firefox 23 on a USB stick. Both are running, but SP6 doesn't know Firefox exists and so won't install the plugin. How can I overcome this?
edit: sorted it. When I figured out to click Mozilla Firefox Portable and then on Install - I'm getting slow in my old age - when I pointed it to portable Firefox, it kept jumping to other executables in the portable Apps folder but eventually I got it to install.
