O.T. FF browser issue?

I have a Dell XPS 8500, with Windows 7 Professional, SP1,
with Spywareblaster, Malwarebytes, Avast , Windows Defender
and Windows firewall.

I also have

I have a Dell Optiplex 780 Tower, with Windows 7 Professional,
SP1, with Spywareblaster, Malwarebytes, Avast , Windows Defender
and Windows firewall.

Intel (R) Core 2 Duo 2.93 GHz
4GB RAM, 750 GB HD

and (external hard drives)

Seagate Backup Plus 1(TB) 2.5 USB Portable HD

WD BLACK SERIES WD2003FZEX 2TB 7200
RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal

The problem is with the 8500 since I only use the 780 as
a backup computer. I've mentioned this before but it seems
to be getting worst especially with the Fox news site.

http://www.foxnews.com/

When I click on a story it cycles and cycles,. and when
it finally opens it keeps cycling through the story. Often
I have to copy/paste the story to You Tube just to listen.
Other times when I click on stories they don't open. I was
just on ebay and all of a sudden music started playing! I
only had ebay open and I didn't click on anything! Now how
does that happen?

In passing, I hate that now they put ads in the the story
so your constantly interrupted.

If I remember correctly, part of the reason FF has
slowed is because they changed and now are more like
Chrome where I have (4) FF exe all running at the same
time.

I've run all the scans and I don't detect any malware
but am puzzled by how long some pages take to load now
and this pop-up music on eBay.


Thoughts/suggestions?
