Search: Cursor jumps to address bar

Hi all, when opening a new tab, i activated the Google Search engine to search for content, yet when i start typing in that Google Search, the cursor immediately jumps into the address bar and searches there (which i dont want of course, this breaks the search engine altogether). Is there a way to make the Search engine work and not let the cursor go into the address bar? Even copy and paste into the Search engine doesnt work anymore. Regards
