2 questions: upgrading and moving

1. Understandably, there is a delay in the release of new versions of Firefox Portable compared with Firefox regular, so my portable installation nags me to update before the update is available here, and offers to update for me (but, I'm pretty sure, it thinks it's a regular install and wouldn't work). I usually ignore it, but today it occurred to me that maybe upgrading that work might work? Or is it better to continue to wait until the new version (in this case 72.1) is available here?
2. I'm getting a new computer and my experiences with Firefox Portable have been so good that I want to install regular Firefox on the new one instead of continuing to run off an external harddrive. Are there any instructions on possibly moving over all my profile, bookmarks, plug-ins, etc. from Portable to regular install? I know there's instructions on the opposite---moving regularly installed data into a portable install, but I'm not sure if the reverse (portable to regular) would work. My guess is that bookmarks and even preferences might work, and not plug-ins, yes? And where?

Thanks!
