Firefox hangs while loading pages.

Question

When loading a new page (not always in a new tab, not always an additional tab or tabs, but it seems to happen more when opening multiple tabs) the little rotating circle will either remain dark and if an attempt is made to reload the location bar changes to new tab, losing the address in the location bar, or the rotating circle will go one way, then reverse, then continue to spin. At the bottom of the page where what is being loaded in a page shows it will hit on one thing (as I'm writing this in Chrome I'm loading a folder of bookmarks I've been loading daily for years that now is a nightmare and pages are stuck at "connected to ajax.googleapis.com," "connected to hell.myfonts.net," "waiting for dt.adsafeproteted.com," "connected to log.pinterest.com," "connected to cdn.syndication.twimg.com," "waiting for api.lanistaads.com," "waiting for www.projectwonderful.com," "transferring data from v4.moatads.com," "waiting for aax.amazon-adsystem.com," "connected to aax.amazon-adsystem.com," and the other three pages are stuck trying resolve the actual URL) and then refuse to go any further. After that the page will sit, unchanging, as best as I can tell forever. I've left a page loading for several hours while working and it was still connecting to googleanalytics when I came back. It does the same in safe mode. Not a single page in the book marked folder is loading, NOT ONE. They're all sitting and spinning either with blank pages or partially loaded. I will reiterate before someone suggests I not load so many pages at once that I've been loading this particular folder full of pages for at least five years and probably longer and it did not do this until the last month.
This has been going on for a while and has made Firefox worthless. It is getting worse. I have read every similar question and none of the answers has made a bit of difference.
I have tried safe mode.
I have refreshed Firefox.
I have uninstalled Firefox and installed the latest version.
I have cleaned my registry.
I have cleaned my cache (which was almost empty anyway).
I have deleted all temporary files that were not in use on my computer.
I have deleted the install folder in Programs(x86) and then reinstalled the latest version (this made everything even worse and resulted in no secured connections being available at all, including mozilla.org giving me not safe connection warnings so now Firefox is even less useful than before) and currently have no add-ons or themes installed.
I have run Spybot, Malwarebytes, Housecall, and several rootkit detectors with no luck.
This computer is less than a year old, is running Windows 8.1 and is up to date. I just installed Firefox v 37.0. When I went to look and see what the version was Firefox can't even seem to resolve its own update URL.

Answer 1

I get an e-mail with go-comics and the ones I want to post links to I'll open in the browser as I read them in the e-mail so I regularly have a dozen tabs open (all the same site) by the time I'm through the e-mail. Every third or fourth page will hang up on something (connecting to or waiting for) sometimes not loading a single image, sometimes loading half the page, sometimes loading everything but the comic (because, hey, why put that as the first thing to load when you've got all these ads and crap to throw at your paying customers?).
At some point a couple of months ago I got some malware associated with trovisearch (I do not know how that got past security and java blocker but it did, probably some hidden crap in something from CNET) that somehow spoofed a page for Housecall and added five or six pieces of malware and adware. I cleaned for two days after and still can't find anything left on the computer even though I've been running scans constantly to try to make Firefox work right. I downloaded and ran a scan using Kaspersky during that time and then uninstalled it. That very well may be the cause of the post-refresh SSL issue.
I have Spybot and Malwarebytes scan logs from the time of the infection if that would help in any way. It doesn't look like there's a way to attach .xml files in this forum, though.
I can also run hijack this and copy and paste if that would help.
I'm currently running Windows Defender and rely on that and Noscript and adblocker plus to keep me isolated from most attacks (I don't have those add-ons re-installed yet). I also run Peerblock because they add malicious sites and known hacking sources (like Chinanet) to what they block as well as all the fake p2p stuff that's constantly pinging the computer. If I'm treading around in perilous waters I run Sandboxie.
Chrome is working as normal but Firefox feels like dial-up or worse right now and without adblocker I might as well be using IE.
