Identifying your problem area
To be able to identify if it's Thunderbird or Thunderbird extensions you need to disable all Thunderbird extension you have installed and enabled. You do so by starting Thunderbird, go to "Tools", select "Add-ons" and disable all extensions listed there.
Quit Thunderbird and start it again. Recreate whatever you did that caused the problem your experiencing and see if it persists.
If the problem persisted go to "Debugging Thunderbird".
If the problem did not persist enable each extension and try to recreate the problem then disable the extension you just enabled again until you come across which extension is causing the problem then go to "Debugging Thunderbird Extensions".
