Oh crapola.

I did try the Firefox newsgroup but it failed to post !

I warned you (in my response to Ross).

That's why I posted here.

No one could know from your starter post that you first attempted to
query the Firefox (FF) newsgroup before coming here hence the suggestion
to go there.

Read my post for those who did not!
If I restart Firefox, how do I get to the download folder ????

If YOU cannot remember where YOU chose to store a downloaded file then
start using a default folder specified in the web browser. That way,
you'll know where is the downloaded folder because it'll be in the same
default folder.

If you can't remember where you decided to store a previously downloaded
file then configure Firefox (FF) to default to the same location. You
can even define what is that default location, so you should be able to
remember that one (when using Windows Explorer to go there instead of
loading FF to then open the folder).

You could even create a shortcut to that default folder on your desktop,
in a toolbar in the taskbar, in the Start menu, or wherever you like.
That way, you don't even have to load FF to find your previously
downloaded files.

Now to make matters worse, on another Win XP laptop, if I download
something the Menu Downloads give me a blank screen. But it did
download because Everything finds it (knowing the name of the download
or keeping Everything active and sorted on Date while I do downloads.)

You are looking at the *history* of your downloads. FF is not a file
manager. It is not opening a Windows Explorer instance. Yes, renaming
"Downloads" to Download History" would be more accurate. FF is showing
you a history of what you previously downloaded. That history is
independent of what is actually residing *now* in the folder within the
file system. I have a history of my car repairs one of which was to
replace the battery. That has happened twice. The battery that is my
car now is not the one recorded in my history for the first battery
change.

Perhaps on that different computer you configured FF differently, like
having it purge its local data upon its exit. I don't use FF 52 ESR.
Since I am using Windows 7 -- one of the newsgroups to which you decided
to CROSS-post with no hint in your starting post about which OS you
really use -- one of the cleanup options in FF 61 is to delete the
"Browsing and Download History". Well, if you purge that data on
exiting FF then it won't be there the next time you load FF. I suspect
that same cleanup option is available back in FF 52 ESR.

Latest Firefox ESR is the Win XP compatible version supposedly.
Latest download means I just downloaded Firefox ESR and installed it.
What else can it mean?

Geez, how about SAYING you are using FF 52 ESR. That's more detailed
than saying "last version" for an OS version that you NEVER IDENTIFIED
in your original post. You CROSS-posted to multiple Windows version
newsgroups, so how the hell could anyone tell if you meant to ask about
using FF on Windows XP or Windows 7, huh?

Mozilla stopped support FF on Windows XP, so the "last version"
available on that OS is Firefox 52 ESR. Mozilla still supports FF on
Windows 7, so the "last version" available on that OS is FF 61. "last
version" could be 52 or 61. "last version" does not say WHICH version.
You never mentioned your target OS in your starter post! You
cross-posted to multiple newsgroups dealing with different versions of
Windows. Don't expect others to know what you don't tell them.

How about *you* read your own starter post while noting to WHERE *you*
chose to CROSS-post.
