I'm feeling rather dumb today.I can't recall and cannot find - after extensive searching (here and across www) how to migrate my Firefox settings, extensions, cookies, etc. etc. from one release to another.
I've a lot invested in Firefox and I hate to have to restart, as in a new installation. I learned how to do bookmarks some time ago, but I can't find out how to migrate the rest.
If someone could point me to some instructions I'd appreciate it.
