Dear Friends,
I need to find a way to copy my firefox and opera user profiles fom my machine for use on another machine.
Secondly, I would like in general to do something like a CCleaning (as in windows ccleaner) and/or a defragmentation, so that the memory and storage are as problem free as possible. Is this possible or necessary on linux mint?
Thirdly, through unknown combinations of keys, I have managed to get firefox to squeal each time I switch sites.... and Opera no longer has a scroll bar. .... I would like to fix these problems before passing on the computer.

I thank anyone who takes the time to help me with at least one of these things.
Janelle
