Does Thunderbird work in TB Safe mode (see Thunderbird Safe Mode)? NO

   Do you use anti-virus and firewall software? What is the version?

Webroot 9.01.35

   Who is the email provider?

Roadrunner and Bluehost

   Who is the internet provider?

Bluehost

   What is the exact error message?

Can't see the emails, just the accounts and folder names on the left, but emails don't display

   What steps did you take right before this happened? 

update Thunderbird

Compacting the Inbox did the trick. I guess I have too many emails in the Inbox folder. Thank you!

Problem is back. It only works on safe mode with everything disabled. This error appears on the console: Timestamp: 8/20/2015 11:23:06 AM Error: DEPRECATION WARNING: Encoding to non-UTF-8 values is obsolete You may find more details about this deprecation at: http://bugzilla.mozilla.org/show_bug.cgi?id=790855 resource://gre/components/mimeJSComponents.js 438 MimeConverter.prototype.encodeMimePartIIStr_UTF8 null 0 null

pscolnik,

You were usng the Lightning/calendar addon at the time. Are you still using it?

I'm having the same problem. When I start Thunderbird in safe mode everything looks very normal. I'm running: Windows 10, Kaspersky Internet Security 16.0.0.614(c), Internet provider is Charter, most emails are at hotmail.com but I've got a few non-hotmail addresses set up too. Help?

Diagnostics are as follows (was captured in TB safe mode):

I'm having the same problem. When I start Thunderbird in safe mode everything looks very normal. I'm running: Windows 10, Kaspersky Internet Security 16.0.0.614(c), Internet provider is Charter, most emails are at hotmail.com but I've got a few non-hotmail addresses set up too. Help?

So you only see the folder list on the left panel? What happens if you *remove* the calendar addon 4.0.3.1 that you have installed?

I had success by starting Thunderbird in safe mode, putting a check mark next to "Disable all add-ons", then clicking Make Changes and Restart. Everything has been perfect since!

I wonder if part of the issue is that I've had Thunderbird installed "forever" (shortly after Eudora's final release) and probably have some very old settings floating around.
