It sounds a bit like a losing battle, but I feel your pain.  In fact,
since I know of no way to install those 4 Firefox add-ons I
mentioned without getting Firefox up and running 1st, it's the old
"chicken and egg" problem.

Slackware 14.2's Firefox spawns 3 (IIRC) tabs that have some useless,
slow-to-load content.  If you can get past that, I can't imagine what
Firefox would be sending.  Oh, wait!  I just remembered that I went to
"Preferences", "Advanced", (via GUI or direct URL
'about:preferences#advanced') then "Data Choices" and disabled the
"Enable Firefox Health Report".  Can you get that far with Firefox or
is it too bogged down to even do that?

I wonder if it might be worth trying to configure Privoxy (you _do_ run
Privoxy, right?) to pretty much block everything, at least to the point
where you could download NoScript, etc.

I suppose once you find where the traffic originates, you'll be better
equipped to block it.

I wish I had better advice to offer.  But I'll keep my fingers
crossed!  Let me know if you want me to try anything.  I've got
Slackware64 14.2 running Firefox 45.3.0 here too.
