@ boof:-
You may well end up losing data, and have to start again, but I would
strongly recommend following Dan's advice, and using Fred's 'portable-Quantum'. There's a very good reason for doing this, and, once again, it's all down to Mozilla changing things without warning.
Referring to bigpup's link above, it appears that from FF 67 onwards, Mozilla have decided that every time you do a fresh install of Firefox, you
must have a brand-new profile. Whether they don't like the idea of 'sharing' profiles, I don't know; I suspect this is more to do with newbies and those with not much experience installing FF, to make things 'easier' for them. Those of us who know what we're doing, it's simple enough to share a profile.....probably more so in Puppy, since we're not lumbered with quite as many 'sudos' and permission/ownership problems as mainstream distros are, and Pup's sym-link function is very easy to use.
The point being, that if you use the 'portable' version, you only have to set everything up
once. After that, you can then 'share' the entire browser between as many Pups as you like, by the simple expedient of clicking on the start script
inside the browser directory. All your bookmarks, extensions, settings, etc., stay exactly the same.....and you're always using the same, single profile, because it doesn't count as a new installation.
(And since my 'portable-FF' install lives in one, fixed location, it means I can use a common, custom-made MenuEntry in every Pup for that browser......the browser will always be in the same location, and I have a .desktop entry I can drag onto the desktop that will always work.)
Just a few ideas; I hope that clarifies why these 'portables' are such a good idea for us here in Puppy-land!

EDIT:- Reading further through Mozilla's documentation, it looks rather like they want to discourage the use of 'shared' profiles. They say it helps to increase stability, but, at bottom, they would prefer you to 'share' profile data by means of the 'Firefox account', which 'syncs' your data between browsers in very much the same way that Chrome always has since the beginning.
I've used Chrome's 'syncing' function for years. It duplicates & mirrors things perfectly between installs.
I tried the Firefox variant of this a couple of times when it first came out. Oh, you get all your data - eventually!
- but it never puts stuff in the same place twice. So you're
still hunting around to find things.
Needs more work, Mozilla. And that's why I prefer the 'portable' version of FF-Q.)
