I am on a brand new fresh install of Windows 10 Home (10.0.10240 Build 10240). New machine only a few weeks old with SSD system drive. Intel Core i5-6600K @ 3.5GHz. BIOS AMI F2, 2/72/2025.
Everything else runs fine. No other identifiable problems on this clean new install and machine.
I am on the release update channel for Thunderbird. Version 38.2.0, just upgraded to a new version while getting this thing posted. No relief from the upgrade, which I can't see at the moment because Thunderbird is hanging as I write. It just came back, I clicked the hamburger to see what version, and it started hanging again before I could get the answer. OK, it came back again. 38.3.0.
I do not have any product from Norton, Symantec, nor McAfee. I have MalwareBytes Antimalware Premium and Panda Free Antivirus. The problems with Thunderbird started before I installed Panda Free Antivirus.
Freezes ('not responding') / hangs are frequent and generally several minutes in duration. I may only get a few seconds of activity before the next freeze.
I added Thunderbird to the windows firewall approved programs list. No help. I added Thunderbird to the exclusion lists for malwarebytes and panda. No change.
I work remotely so email is my lifeline. I have installed another email client and will soon uninstall Thunderbird. I've used Thunderbird for some years now - at least a decade, probably more. So I am not new to this.
Current add-ons - .vcs support 0.6.4; configdate 0.75; lightning 220.127.116.11; lookout 1.2.13; smile fixer 1.4.1; Sticky Password Autofill Engine 18.104.22.168.
Trying safe mode right now. It has run for about 3 minutes straight from startup time, which is pretty good compared with recent difficulties. I'll post an update in a bit.
Update: went maybe 10 minutes without trouble in safe mode. So I went back into normal mode and disabled several of my add-ons - .vcs support 0.6.4, configdate 0.7.5, lookout 1.2.13, and smiley fixer 1.4.1. After a few minutes it has hung/frozen again, so it must be sticky password autofill engine 22.214.171.124 or Lightning 126.96.36.199, I guess.
Update 2: disabled sticky password autofill engine. Thunderbird still hanging. Must be lightning. Will disable and restart.
Update 3: disabled lightning. It went a good long time - perhaps 15 minutes - but is finally hanging/frozen. I guess I'll go back to safe mode, which seems to be quite similar to what I've done already (disabling all add-ons). Should have the same result as manually disabling all the add-ons, but maybe not!
Update 4: operated for some time in safe mode, but it is hanging / frozen / unresponsive again. I'm open to suggestion. Opera Mail, or just about anything else, is looking pretty good.
