There are several ways to open multiple web pages.
- Bookmarking web pages to a folder, navigating to folder from bookmarks menu and clicking Open All Folder Items.
- Bookmarking web pages to a folder, giving nickname to folder and entering nickname in address field or setting nickname as home page in Tools > Preferences… > General > Home page.
- Opening web pages, saving them as session File > Sessions > Save This Session… and opening it File > Sessions.
The advantage of sessions over bookmarks is it can store several settings (zoom, fit to width, images, etc.) per tab.
Sessions can be opened quickly by assigning it to a Speed Dial slot.
