Re: Firefox +1 Mega Thread
If I understand what you mean by speed dial (tab with sites you graphically bookmark). then I too had problems with the Firefox feature. I replaced it with a plugin called "new King Tab", which works much better in my opinion. I have "tell websites I do not want to be tracked" enabled but it still displays sites in history. It will display as a list or graphically or as RRS feeds.
