Error with TB3:
threadvis-jserror
message: this.getMainWindow().GetLoadedMsgFolder is not a function
file: chrome://threadvis/content/ThreadVis.js
line: 263

ThreadVisNS.ThreadVis.prototype.checkEnabledAccountOrFolder = function(folder) {
if (! folder) {
folder = this.getMainWindow().GetLoadedMsgFolder(); //This is line 263
}
if (! folder) {
return false;
}

// get from cache
if (this.cacheKeyCheckEnabledAccountOrFolder == folder) {
return this.cacheValueCheckEnabledAccountOrFolder;
}
