If you have a floppy drive and at least one blank
floppy diskette, memtest fits quite nicely on it.

Some users complain if I mention "floppy", because
they don't have one, or "it's too archaic". Most
of the capacity of a CD would be wasted. But, it's
convenient if you have discs handy.

I use floppies for my copies, and for the machine
that doesn't have a floppy drive cable, I use a
USB floppy drive instead (an external device).

So I don't have a problem with floppies. Once the
boot process is complete and the screen is 640x480,
you can pop the floppy out.

You might have Firefox 57, since WinXP stops at
Firefox 53, and lucky Windows 7 users get to
continue receiving updates.

Firefox 57 is called "Quantum" for some reason,
and it is a multi-process version. If you look
in Task Manager, you might see four instances
of the word "Firefox" in there.

That's not supposed to slow the machine down.

You might use Task Manager to see if anything
in the machine is mis-behaving (using a lot of CPU).

Firefox will use something like 20% more memory than
the previous version.

The new Firefox is modeled after Google Chrome, and
that's why it has four processes running minimum.
Because Chrome does the same thing. Firefox already
used a Container concept for the Flash plugin (plugincontainer.exe?),
so that if Flash crashed, the browser remained running.
The multiple processes could be used for Process Isolation,
but I suspect that's not really all that practical when
the processes also have to talk to one another. There's
still a possibility the set of processes could freeze or
deadlock, depending on what flaky thing happens.

You can turn off that new feature if you want.

In the URL bar, enter "about:config".

In my copy of Firefox 57, I can see

    browser.tabs.remote.autostart     False
    browser.tabs.remote.autostart.2   True   <--- change to False, to make
                                                  Firefox run a single
                                                  process

You can double-click the entry in the table,
to "flip" the state of a boolean variable
like that one. Once that's done, the next time
you start Firefox, it should behave a little
more like the old version.

But the ugly icons (you know, the issue with
the folder icons in bookmarks), those icons
are now there to stay. The only way to revert
the appearance of the browser, quickly, is to
use an older version. It's not clear
to me whether any "themes" are available
as WebExtensions or not, to go back to the
old icons.

And by all means, use the Task Manager to survey
the state of the machine, when it feels "a little slow".
There might be a reason - something that needs to
be fixed. It might not be Firefox at all.
