Blink - Batch Link Opener от Sebastiaan du Toit

This tool adds a marquee-style selection tool you can use to open batches of hyperlinks quickly.

This tool has two distinct modes, both offer the same underlying functionality but will change the way the marquee tool is drawn. These modes can be toggled with the Tilde/Grave key, usually located above the Tab key on US/UK QWERTY keyboard layouts.

Mode 1, Viewport mode:
As the name would suggest, Viewport mode works with what you can currently see on screen without scrolling. You'll notice that if you do use this mode and scroll the page that the tool will "float" in place over the contents underneath.

Mode 2, Fixed mode:
This works much the same as Viewport mode, but instead anchors the starting position of the tool to page allowing you to extent the selection of the tool while scrolling.

Once you've settled on a mode to use, to activate the tool you simply need to click and hold down the Right Mouse Button then start dragging the cursor to draw the marquee rectangle. Once you've covered the links you wish to open, releasing the Right Mouse Button will open your links.

Both modes will open your selected links in batches of 10 links (by default). The first batch of links will open immediately while links that fall outside of the initial batch will be sent to a queue which you can then open once you're ready to proceed.

You can change the batch size in the Options page of the extension.
