I had to do it once and afaik it worked: just making a tarball of .mozilla and putting it on the other machine in my home worked.
When you think about it, if you make backups of that .mozilla, you have to be able to restore it, no? :)
Let us know if it goes well!
I have just got back from holiday and now want to get around to changing from RH9 to FC1..
The only thing that I am not sure of is moving my Mozilla mail and news mail stores, account setups and rules to the new system..
Will it simply be a case of copying the ~/.mozilla directory to the newly installed system?
Would be nice if Mozilla had and export / import option for moving the data from one install to another..
Thanks for any info..
