Hover over any link for a short time to open it in a new tab in the background.
This hack was inspired by dontclick.it (http://dontclick.it), a site that demonstrates some user interaction techniques that don't involve clicking. The site is written in Flash, which annoys me, but it gave me the idea of lazy clicking: the ability to open links just by moving the cursor over the link and leaving it there for a short time. I don't claim that it will cure your carpal tunnel syndrome, but it has changed the way I browse the Web.
This user script runs on nonsecure web pages. By default, it will not run on secure web pages, because it has been my experience that most secure sites, such as online banking sites, are very unweblike and don't support opening links in new tabs.
The script gets a list of all the links (which Firefox helpfully maintains for us in the

GM_openInTab to open the link in a new tab.
If you move your cursor off a link within 1.5 seconds, the onmouseout event handler cancels the timer, so the link will not open.
If you actually click a link within 1.5 seconds, the
onclick event handler cancels the timer and removes all three event handlers. (Note that you can click a link without leaving ...
