Live chat has helped get rid off unwanted tabs on most of the web sites,except yahoo's.I once had posted a similar question and had never been able to even find my own question when tried the"search" option on this forum page....then tried post another question with simple header"Single tab" and used the search key option,search option answered:" 0 found"...had scrolled through 26 pages then finally saw my own question"title"....just want to share this with any one whoever happens to read this....try live chat....not easy..about 50 tries then once saw:"we are open",other times:"we're closed". Anyone including FireFox support team can help finetune the forum "search option",then this forum won't be so many unecessary postings;less crowded. I think.
