Here we add a new field called `Browser Title` to the page edit view after the title field. And after that we render that field value into the browser with a TypoScript.
After successfully implementing the scripts you should reinstall the plugin from the Extension Manager Module then only the database table get updated according to the ext_tables.sql file.
This will render the new field in the backend page edit view after the title field.
This Typoscript will render the browser field content in the frontend. What does the script exactly do is render the new field in the title tag and if there is no browser content then it will render the default title field.
Adding new field to the database pages table.
