The problem here is even if you go in and disable "open in new window" by adjusting another setting it'll just open the link in the current tab/window :(.

There might be an extension that can disable opening links with middle click completely rather than replacing autoscroll entirely, however I cannot find one. I know the code exists (by looking for auxclick and preventdefault()), but it doesn't seem anyone has written one yet.)

You will have to make sure that you do not middle-click on an element that accepts a mouse click. Only if you click in 'free space' you can activate auto-scroll.

For some reason clicking on an active element happens for me a lot of times when one window (e.g the developer tools in a standalone window) is active and is on top of another window that I want to bring up front with a click in this window instead of using Alt + Tab or other ways.

http://kb.mozillazine.org/About:config_entries#Browser. browser.tabs.opentabfor.middleclick Determines the behavior of a link when middle-clicked. True (default): Opens link in new tab False: Opens link in new window

As you can see False does not mean you are turning middle-click off but rather open links in a new window.

Still, there should be an option for disabling middle-clicking links altogether. People have requested this for the past 15 years.

On some sites, such as ArtStation, links can cover 90% of the page making it very awkward to use AutoScroll.

Try to middle-click the scroll bar to see whether that works.

That is already what I do. Which partly renders it useless as I could just use the scroll bar itself instead.
