I tried to ask on apple but it didn’t work so I had to do it here. First when I am trying to clear my history it shows how many tabs I have open but this time it says “This will close your 3 tabs” while I only have one open. I think this is a hacker
What device are you using?
Any other apps running that might be using safari?
If using a Mac, maybe post this in the Mac forum board for better exposure to Mac users. https://community.norton.com/en/forums/norton-for-mac
