This started about a week ago. I upgraded to 32.0b8 to no avail. I close and FF it tries again to re-download all previous download entries... My add-ins are Download Helper and ABP. My AV is MSE. My PC is a 6gig core i5 Lenovo on Win7-64bit. This has me puzzled, I run a tight configuration with no malware or toolbars etc.. and I have a good Cisco router with all DNS requests routed through OpenDNS family shield. Note - After closing FF, I check Process Explorer to make sure it closed right and then run CCleaner. I restart FF and it immediately wants to re-download all files previously in the list... Even though before closing, i verified all files (some PDF's) were downloaded and intact. Also, the X icon in the download panel does nothing now... so after rebooting FF I can select a pending download and hit the delete key and that works... However this is getting old very quickly.. ;-)
