@sock Hmm... I wonder if you have malware in your Chrome. If I were you I'd uninstall that app and then uninstall chrome completely. Restart and then reinstall Chrome. Your account should be backed up so you shouldn't lose anything. If the Twitter app returns then I'd be suspicious of your add-ons. One of them isn't what it seems...
@sock Then a reinstall and restart will hopefully suffice. Thank you for sharing so I can be in the lookout. The warning is appreciated.
@danielbsmith Not likely. I don't use plugins. I am very careful about such things.
