PDF Viewer with tabs

Foxit Reader has multiple-tab support:

However, this is only for separate PDF files, not chapters within a single PDF file, so you won't be able to do this directly in the Foxit UI. However, you can come at it by getting your PDF into multiple files and then opening these as tabs in Foxit Reader. You can do one of the following to get your PDF into multiple files:

• If disk space is not an issue, just make separate copies of the PDF file.
• If disk space is a concern, use NTFS Link to easily create hardlinks of the original file. These will open up as separate tabs in Foxit.
• Use PDF Split and Merge to split the PDF chapters into individual PDFs

No, there isn't. There are PDF readers (e.g. Foxit Reader) that can display different PDFs in separate tabs, but none of them can display different pages from the same document in separate tabs.

If you're using Adobe Reader then Alt + Left or Right Arrow will take you to the previous or next view, if you just want to flick between two pages.

You can use Okular pdf reader. It can be installed with following command if you are using apt package:

sudo apt install okular

After installing Okular, you need to enable the multitab option as explained here.

Settings > Configrue Okular... > Program Features > Open new files in tabs

You can open the same document in the same window by drag and drop in different tabs.
