I have been forced to create a new profile because, after an update to version 17.0, Firefox persisted in opening tabs from the previous session. Unfortunately another problem developed, namely, the constant appearance of a series of thumbnails in a new tab, a facility that I definitely do not want. After consulting Mozilla help and forums I tried all of the suggested solutions to no avail.
I eventually went about:config browser.newtabpage.enabled and rendered it false. The annoying thumbnails have disappeared!!!!!

this is also documented in the New Tab Page - show, hide and customize top sites help article (see the section "How do I turn the new tab page off").
I had already tried this and it did not work for me.
I take it that this is spam.
Yes, that post was spam and I've removed it.
You can create these Boolean prefs on the about:config page if you want to disable the thumbnails on the about:newtab page.
- name: browser.pagethumbnails.capturing_disabled with value: true
- name: pageThumbs.enabled with value: false
What does "pageThumbs.enabled" do?
