....only to find that they have not only removed/deleted all your list of "Favourites", but also installed themselves as your Default Home Page!... >:(...!!
I have had this "trouble" before, and had to search through the inner workings of my Hard Drive to locate the place where my "Favourites" are hopefully stored, and attempt to restore them to my Browser again...
I am now trying to set fire to the "Google" Browser Page, and replace if with my usual "Orange" Browser Page...
...and searching for my missing list of "Favourite" Sites...
My whole Browser has gone to pot!!
...arse...

It gets more difficult each time!
There are times when Mr. Google is more trouble than he is worth!
F.... 8-)...!
P.S. ....With Win XP SP1, is there a way to restore back to my previous Mozilla Browser Details...?
