I forgot about the CTRL + Mouse Click feature in Firefox until someone pasted it into my comments a couple of days ago.
Basically if you hold down the Control key and click on a link it will load it in a new tab in the background. So, when I’m reading a good blog post with five links in it I just hold down CTRL and open like 20 windows in the background and then use CTRL-W to close TABS as I read them.
It’s so efficient it makes me. so.. happy. Totally life changing.
