I found myself opening the same tabs every morning like a robot, so I decided to create an Ubuntu dock item to automate it. You can edit the tabs being opened in the .py file.
.desktop file must be placed in {user}/.local/share/applications
Right click on icon and add to favorites to add icon to Ubuntu dock.
Requires Python.
