Is it possible to open the same PDF multiple times with Adobe Reader?
Slight addition to serhio's answer.
In Acrobat Reader DC (released in 2015)
- Open your document;
- Go to the
- Drag and drop the tab of the new window on to the tab bar of the old one.
Then you have two tabs for the same PDF file.
I think it's a great omission on the part of Adobe not to include a "Duplicate Tab" feature.
