> You are aware that current BLFS has Firefox 45, not 38, correct?

Yes, Chris, of course, but I'm still working on building a 7.7 system
that recommends -36.  I wanted to upgrade that a bit.

Certainly, Ken.  Firefox has been known to have flaws needing attention.
I was hoping the ESR would be a "better" release.  Unfortunately, IMO,
since they've gotten on this "rapid release" kick, the quality of the
builds has gone down, "Don't worry about it, we'll fix it in the next
release."  NOT!  I just tried -39 and it failed in the same place.  One
wonders how THEY get their binaries built...

;-)  You guys throw them away and go on to the next too fast to matter!

> I think Andrew is right - the link probably needs more space.

Nope, even when this most recent -39 try finished it had 7.6GB free

That RAM is obvoiusly per make job.  I was running 6 on my 12GB i7, and
top in another xterm.  I saw up to 42.5% memory commitment from top.
That's fine, never want 100%!

I don't know, going back to -j1?  That'd be slow, but no slower than
trying for more than a day on this...

I compiled -35.0.1 on my 32-bit 7.2 system.  Don't know how that

p.s. finally got my digest, after 2PM PST.  Ususally comes at noon.
