I am unable to open Thunderbird at all - it just keeps crashing and asks me to send a crash report.

more options

My Thunderbird e-mail will not open at all! When I double click the icon to open it, I just get a dialog box saying "Sorry, Thunderbird has crashed and is unable to open." (or something similar). It then offers a box to check to send an error report to Mozilla support (which I thought wasn't supporting Thunderbird any more...?) Then there is a choice to restart or quit Thunderbird.

I have done this multiple times. I have also shut down my browser and rebooted. Nothing has helped, I still get the same dialog box but have not received any response. I have to log into Xfinity on the web to see my emails -(I have a "comcast.net" address).

I just got back from vacation on 7/29/21 when this started happening. Thunderbird worked fine before I left on 7/12/21. I am wondering if this has anything to do with the new version 78 which I understand is being released some time soon to existing users.

Does anyone have any suggestions? Your help is greatly appreciated!! P.S. I am not well-versed in computer technology. Thank you!!

To Matt and sfhowes,

Thank you both very much for taking the time to send suggestions. I explored all of them. Nothing I did seemed to help. HOWEVER...

It turns out, all I needed to do was simply to download Thunderbird again! This took less than 10 minutes, and Thunderbird opened just fine, with all data intact. PROBLEM IS NOW SOLVED!!! HOORAY!

The only reason I didn't do this before was that I thought I would lose the custom folders that I had set up in Thunderbird, of which I have about 30 or more. I found out today when talking with my AVG support that I wouldn't. Just goes to show, for those of us who are "technically challenged", we just need to be persistent!

Thank you again so much. I really appreciate your time and efforts to help!

Some crash ids would be helpful in allowing someone to look up what you have been submitting. See https://support.mozilla.org/en-US/kb/mozilla-crash-reporter-tb#w_viewing-reports-outside-of-thunderbird

Matt, I have tried twice now to send two crash reports back to you and both times I get an "error", try again!

Here's the last crash report: 7/30/21 - 3:49 PM

I can send the first one later if needed. Hope this gets through!!

Based on this support thread it might be you need to scan your hard drive for errors using the operating system tools. https://support.mozilla.org/en-US/questions/1319184#answer-1385153

You might want to do the system check mentioned here https://support.mozilla.org/en-US/questions/1311551?page=3

While it is a Firefox thread the crash signature is the same and it appears to have helped in that instance.

Disable the AVG Mail Shield or remove AVG entirely and see if TB still crashes.
