Remove browser header and footer in PDF documents

Hello everyone,

we have PDF documents that received the following headers and footers when created by the browser:

1. Top left: Firefox

2. Top right: Internet address

3. Bottom left page number

4. Bottom right: date with time

Unfortunately, this content has not been set as a header and footer, so one cannot simply remove the content by removing the header and footer. The content is on the outer edge.

Now our question:

How can we find and remove this content? Is it possible to search and remove the content based on the position in the document? Is it possible to create a macro using the action wizard so that this content can be automatically removed from hundreds of PDF files?

Many thanks for your help!
