I updated to 78.5.0. And now Thunderbird doen not start at all. I get an tiny grey window telling : Parser error : XML-parsefout: ongedefinieerde entiteit Locatie: chrome://messenger/content/messenger.xhtml Regelnummer 901, kolom 3: 

 <key id="openLightningKey"
</pre>

--^ "

and I have no file "messenger.xhtml"  in thunderbird Chrome, in fact the whole messenger map is not there. So I cant remove line 901 either. 

Who understands what went wrong ? and what to do 
Thanks 
Ferdinand

As I can't start I cant apply the solution you proposed for the other case.

Open the profile folder, which is located by default in:

C:\Users\username\AppData\Roaming\Thunderbird\Profiles\randomstring.default

AppData is hidden by default.

Open prefs.js in a text editor, look for the line

user_pref("gfx.direct2d.disabled", false);

change false to true, save the change, then start TB (if you can).
