Problem with new tabs.
When I open a new tab, it doesn't display the sites well. Everytime I start firefox, I have to go to the 'about:config' page and manually change the value of 'browser.newtab.url' to 'about: newtab' to get the right page.

What is the value in 'browser.newtab.url' when you start Firefox?
When I start it, it always says 'about:blank', no matter what it was last session. However, when it is changed, it keeps that value until the end of that session.
Well, all problems seem to have disapeared for now, without doing anything...
