If you have a 3 button mouse, click the scroll wheel and it should open in a new tab. I know this works for sure with my mouse, and I've tried it on a few others, but I'm not 100% sure if that's something that's default on all mice or not.
Worth a shot!
I've been looking for a way to open links on the bookmark toolbar in a new tab by default. I know the right click > open in new tab but I just want to open it with the one click. Have not been successful thus far. Anyone know?
