Are you looking for multitab PDF viewer in Linux? Probably you want an alternative for Foxit Reader. Then use Qpdfview. It supports multitabbing. Also, it supports zooming, continuous view, fullscreen, properties viewing, sidebar, and so on. Fortunately, Qpdfview is available on Ubuntu official repository and many other distro repositories. Personally, I’ve used Qpdfview on my KDE as default PDF viewer because I always open many PDF files at once. I hope Qpdfview is useful for you too.
Install on Ubuntu
sudo apt-get install qpdfview
If you dislike to command, use Ubuntu Software Center instead.
