This remains one of the most used extensions for me, and one that is very useful for pasting html code on sites such as Freerepublic.com
As re backing up, sorry to be so long to respond, but i do see the bbcodextra you mentioned in about:config, and its scripts, but which i also see in prefs.js, so if i just copy that it should work.
What i had done is copy the whole profile to a new one, which worked. Thank God for FF and your help to make it even better.
