This is an old problem, but I just thought it would be nice if when I clicked on a link, that it opens up a new tab/window with the link rather than replacing this website with it. I've clicked on links without thinking and lost my place on Allegro.cc.

Change middle click on your mouse. CTRL + click in a decent browser.

Yeah, I usually middle click, Ctrl-click, or right click and choose "Open in new tab". Left-clicking is for people that still use IE

And then I middle click on tabs to close them, or press Ctrl+W. Lots of tabs going on.

I'm such a heavy tab user that I got a mouse with marco keys, and all the macros I set up are basically keyboard shortcuts for dealing with tabs.
I got a CTRL + TAB and CTRL + SHIFT + TAB for switching tabs, F5 for reloading, CTRL + W and CTRL + SHIFT + W for closing and unclosing tabs (sometimes I hit the close tab button by mistake) and two for page up and down because another forum I visits is designed in a why that I use those keys often.
