Like BradC said .. easy just to copy profile from the roaming folder over to new PC, or save this data as your backup.
But the easy two step process to replace Mozbackup is to use Hekasoft.
I also used to use Mozbackup, then switched to Hekasoft.
It does more programs than just TB and FF, but you configure it to do just those two if you want too.
When you first start it up, there is a very long list of software you can backup.
Great if you have all that software, but annoying if you only want to backup the software you have installed(or just certain software .. eg. just TB and FF).
In the settings (Options->Settings) .. go to Modules and deselect all and then select only the software you want it to display for you to backup in it's dropdown list.
Then a bit easier on the mind to work with.
After this, it's basically the same as Mozbackup.
One other option in the settings is to have it use higher compression procedure for it's backup routine. Takes longer to backup, but no worry.
Here's the link to Hekasoft .. free to use. It's donationware.
