A webpage dropdown menu contains items from a previous python programming session


On my WIN 7 laptop I started learning Python3 programming. I installed python and wrote a simple trial program. I did however search the online Python help web pages for several things. Several days later I used Brave to access www.Sharecast.com . I clicked on the top right search box, and to my surprise a drop down menu offered me
" creating a file
getting date and time
python library
python tkinter "
Exactly the things I had searched on when doing Python stuff. Surely this field should get
cleared out initially for a new web page.
I entered “barc” and clicked the search button. The search produced full info on
Barclays Bank , and then added “barc” to the end of the above drop down list ! Further searches added their keyword to the list.
This behaviour does not happen in Chrome or Firefox.
