Thunderbird crashes on start up

[J-Paul BERARD]

When I try to start up Thunderbird (v 1:78.3.2), a information box appears with this message :
"key id="openLightningKey""
This bug happened since yesterday, with Ubuntu 20.10.
It didn't happen at the beginning when I have updated to 20.10

If I start Thunderbird by a command in the Terminal, I get these messages :

[calBackendLoader] Using Thunderbird's libical backend
Extension error: Error while loading 'jar:file:///usr/lib/thunderbird/omni.ja!/chrome/messenger/search-extensions/twitter/manifest.json' (NS_ERROR_FILE_NOT_FOUND) resource://gre/modules/Extension.jsm:570 :: readJSON/</<@resource://gre/modules/Extension.jsm:570:20
onStopRequest@resource://gre/modules/NetUtil.jsm:128:18

Then the message box appears. When I close it, I get :

JavaScript error: resource://gre/modules/JSONFile.jsm, line 173: Error: Data is not ready.
JavaScript error: resource://gre/modules/LoginManager.jsm, line 488: NS_ERROR_XPC_JAVASCRIPT_ERROR_WITH_DETAILS: [JavaScript Error: "Data is not ready." {file: "resource://gre/modules/JSONFile.jsm" line: 173}]'[JavaScript Error: "Data is not ready." {file: "resource://gre/modules/JSONFile.jsm" line: 173}]' when calling method: [nsILoginManagerStorage::findLogins]

Thunderbird opens in safe mode.

Status changed to 'Confirmed' because the bug affects multiple users.

[joe garner (joshyger)]
