Hi,
Thank you for reviewing, Phantasma.

> 1. Adjustable delay, so you don't need to press shift all the time, e.g. when page is full of media-links
This is really great idea. I want to know the example of full of media-links. Did you mean it is the link with an image (e.g. ＜a href="https://addons.cdn.mozilla.net/user-media/addon_icons/1018/1018394-64.png"＞＜img src="https://addons.cdn.mozilla.net/user-media/addon_icons/1018/1018394-64.png" /＞＜/a＞)?

> 2. Possibility to disable audio, image, pdf or video-preview
This is also good. By the way, your problem can be solved just by disabling "another add-on".

Both ideas are very interesting. I will add this feature.
