SeaMonkey bookmarks deleted after Service Pack upgrade

[Rodney Byne]

After the latest upgrade to 6.0.3 in Quirky Tahr, again Quick Setup
Country Settings had changed from my en_GB to US.

More annoyingly, all my carefully prepared bookmarks
in SeaMonkey had been deleted and Adblock Plus
removed in Tools.

Can these changes be prevented in future upgrades please?

Concerning the bookmarks, if you select Bookmarks - Manage Bookmarks and
then select Tools, there should be an option to back up your Bookmarks to a file with a json extension.
I had made a backup of my bookmarks and it saved me when they had disappeared.
I used the Restore option -restore from file, to reinstate them.
This was with Seamonkey.
