re << That should be no problem. >> What should be no problem. How do I get to the authors website? The server at mozbackup.jasnapaka.com is taking too long to respond. The backups created with v 1.5.1 are half the size with FF8 Pre FF8 the backups were twice the kb's Have not changed any MozBackup settings.

I don't have nay problems with accessing the mozbackup.jasnapaka.com site.
It appears instantly for me on Linux.

Can you see the site via Google Translate with a random source language or the Google cache?

Those backups are ZIP archives and you can open them with a ZIP archive manager or make a copy and add a .zip file extension and open them in Windows Explorer to see their contents.
Then you can check which files are backed up in the archives.
