I've checked the Mozilla support sites extensively and not found anything that helped, then I tired the forums at mozillazine.com http://forums.mozillazine.org/viewtopic.php?f=38&t=2824421&p=13491413#p13491413, where it was suggested I try restarting in safe mode, When I did that, it worked, until i re-enabled Adblock Plus 2.5.1.
Any suggestions about how to get Adblock working again?
