Safari opens with old tabs on start up
Safari keeps opening with old tabs from about 3 weeks ago rather than my home page. On start up safari is showing as open and there is a folder in the right hand part of the dock. This has the old tabs in it and safari opens with these and not my home page. I've seen other threads which advise to ensure preferences are set correctly etc but none of this has worked. All settings are for my home page to open and not previous windows. What confuses me is why these particular old tabs are opening. Any ideas how to get rid of them and for safari to start opening with my home page again. Thanks.
