I'm sure you are more familiar with Firefox than me, as I'm only a recent convert to
Firefox Portable. ...However, they are very similar, obviously.
Just slightly puzzled by ".....downloaded a fresh copy but when it ran it didn't pick up my favourites from IE as its supposed to do". ...When you say "ran", do you mean as in "open" program, or "import" IE Favorites. ...If you mean the former, then the problem might be solved by the latter;
'File > Import...'.
