Computer gurus I need help: Weird gooogle javascript issues

[john70t]

(sorry for the long post)

1). Previously I was using the latest FireFox with NoScript only.
The computer would occasionally lock up for 10-30min, until a javascript error popup finally appeared.
I would stop that script, and the computer would function normally.

Typical errors:
Script: chrome://browser/content/tabbrowser.xml:2189
Script: resource://gre/modules/XPCOMUtils.jsm:332
Script: resource://services-common/preferences.js:375
Script: resource://gre/modules/ContentPrefService2.jsm:735
Script: chrome://global/content/bindings/browser.xml:807
Script: resource://app/modules/DownloadsCommon.jsm:215
Script: chrome://global/content/bindings/browser.xml:807
Script: resource://gre/components/nsContentPrefService.js:858
Script: resource://app/modules/offlineAppCache.jsm:16
Script: chrome://browser/content/sanitize.js:137
Script: resource://app/modules/DownloadsCommon.jsm:215
Script: resource://app/components/nsBrowserGlue.js:310
Script: resource://gre/modules/XPCOMUtils.jsm:329
Script: resource://services-common/preferences.js:375
Script: resource://gre/components/nsContentPrefService.js:852
Script: resource://gre/modules/DownloadLastDir.jsm:80

2). I added the Ghostery extension (a Google product) to stop these javascripts and problems.
The same problem would still occur, now more so.
After a few weeks, the lock-ups became quite severe. My hard drive was getting seriously trashed. Even email literally took hours as the hard drive spun and spun.

3). Today I 'disabled' the Ghostery extension while offline.
-A 'Ghostery fix' webpage tab appeared whilst I was offline. Huh?
-I rechecked FF extensions but Ghostery extension was still 'enabled'. Huh?

4). I 'removed' Ghostery this time, restarted FF, and the computer functions just like brand new again.

5). Connected to the internet again, clicked on the regular PPOT bookmark: Off Topic Discussions - Pelican Parts Technical BBS.
It was a blank page. The bookmark had changed. Huh?

6). Did a web search for Pelicanparts, clicked on this link http://forums.pelicanparts.com/off-topic-discussions/, and everything works again normally.

So what causes these javascript issues?
It's just like a DDOS attack.

Update:
This post appears as a blank page, until javascript for 'Google syndication/analytics/other' is allowed.
And several duplicate posts were made while editing.

Strange.

(If anyone knows of a fix I'd appreciate it. This affects my business.)

I installed "Google Ghostery' a few weeks ago. Then uninstalled it. Then some strange issues occured:
-Bookmarks show up as blank pages.
-Pelican post results show up as blank.
-Other pages on the web (i.e. Trulia seach results) show up as blank.

It's odd. This has never occured before.
Nothing else on the computer was changed.
All I did was remove the FF Ghostery extension.
