ini files or other such things…(which don’t work anyway) I would like, for this particular (web) application to disable the default action of the middle mouse button - as I can do for the left and right buttons - for all those people that have javascript enabled and haven’t edited about:config or. disable javascript, which makes all this pointless) People can change the default behaviour of their browsers (e.g.

The behaviour of the brower(s) is not something I’ve configured (default install) other people (outside the company where I work) use browsers that exhibit the same behaviour.Browsers have default functionality - most of the time it’s bad to change that.Thanks for your your visitor can set their middle mouse button to perform whichever action they want it to perform why would you assume that it does what you have configured yours to do in their browser and why would you want to interfere with what they have chosen to have it do. Things like this are so frustrating - I’m trying to convince programmers where I work that web apps can be as good as desktop apps then every step of the way the browser vendors do stuff tlike this… :mad: I just find it odd that I can prevent left clicks, right clicks, key presses etc, but no way to turn this behaviour …even though Firefox and Opera have config settings that say they do… they just don’t Thanks I do know about the event.button - that wasn’t the problem, if I disable onclick, onmousedown, onmouseup (and onmousewheel) the browser still opens the link in a new background tab - there just doesn’t seem to be a way to stop this… Thanks for the Yeh, I could do that but they are links - just “progressively enhanced”, what I wanted to disable was the browsers default action of opening a new tab in the background when clicking the middle mouse button, you get the same result doing right click -> “Open Link in New Tab”.
