I have been working with your files regarding moving Firefox profiles between computers. The instructions listed leave a lot to be desired. I want to move a profile from Firefox on a PC to Firefox on MacOS (SnowLeopard). At this point, when I open Troubleshooting information, Show in Finder, there are now three files there. Two are default profiles, including the one I moved from the PC: 023itdk7.default - which is the folder I saved and moved from the PC; a0ibrn2u.Me - which is the profile I set up according to what I thought the "Managing Your Profiles" and "Recovering important data from an old profile"was telling me to do; and l2usuzu74.default (I don't know where this came from). How do I invoke the one I moved from the PC; or get rid of the other two? Why have I got so many? Your instructions concerning individual actions are fine; but the general ghist of the whole activity leaves a lot to be desired.
