As sunlab suggested I added the option to have a delay while opening links because some sites have problems with multiple request at the same time, the delay is 0 by default.
With the amount of possibilities available to open the links (and more to come like opening the links as private tabs, copy them to the clipboard) plus other options do you think an optional toolbar button displaying a popup for quick access to them is a good idea or a terrible one, making this extension too bloated?
I guess using the Ctrl/Alt key shortcut to open the links in a stack and other key to copy them in the clipboard will be enough for most people but I can be wrong so please post a comment or send me an e-mail with your opinion.
This would be a rough example of the popup:
(The button icon is a template from the Opera extension examples)
