Safari/Google search bar size.

Safari 17.5

Sonoma 14.5

Bit of a strange one for me.

Something has changed and I haven't got a clue what.

When I log into my Google account and open Safari, the search bar has gone really wide.

If I log out it goes back to how it should be.

I have logged into another Google account (my wifes) on my mac, and all is well.

I have tried clearing my cache, etc.

I have started in safe mode....just to try.

I was cleaning my keyboard and screen, I have changed a setting unintentionally somehow.

I have included two screen captures, one with me logged in (wide search bar) and logged out (the default size).

Thanks for any replies.
