Hello. After the recent update that added profiles to Firefox I have gotten them working on my personal computer but not on my work pc. The option for creating profiles showed up once when launching the browser but I had to dismiss it at the time. Now I can't find the option to create profiles any more, I have followed the guides that mozilla have put out but the option physically is not there. I have also tried reinstalling Firefox but that also did not work. what do? Thanks.
