stop xnotifier from checking on chrome start up

I see the open automatically is unchecked, bit on my older laptop, it tries to check the email as soon as chrome is opened. And that for some reason slows down the loading process of chrome. Sometimes it's painfully slow.

Is this a bug or has the installatin gone bad? if I were to reinstall it, do I lose all the information already entered? 

 

Thanks for any insights
