Middle click on link not opening in new tab
Normally, middle clicking on a link will open the link in a new tab - that's what I want it to do. But some days middle clicking on a link will act like left clicking on a link, opening the page in THIS tab instead of a new one (leaving the page I was on). Anywhere else in the OS middle click is acting normally; it's a firefox problem.

Enter about:config in the address bar. In the search panel enter "click" w/o quotes. Make sure browser.tabs.opentabfor.middleclick is set to true.
Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.
- Switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
- Do NOT click the "Refresh Firefox" button on the Safe Mode start window

It is possible that there is JavaScript onclick is involved in the link that overrides this behavior.
Does this happen randomly or can you reproduce this on specific web pages?
I found out that I can reproduce it on specific web pages. Middle click on any of the word rectangles here: http://www.thesaurus.com/browse/bug?s=t (but other links like in the menu etc do not have the problem)
Also, on that page right clicking on links acts like left click too! (But I know I have seen pages where middle click acts like left click and right click acts properly - I know because I was right clicking and choosing open in new tab)
Feels like a bug in firefox because I see nothing odd about the html for those links.
All those links have a JavaScript onclick event listener attached that intercepts all mouse click and opens the link in the current tab.
What in that code indicates to you that the links have javascript onclick event listeners attached to them? (I would like to learn how to spot it)
I wonder if there is an addon to force proper behaviour

The Web Developer extension's toolbar has a Disable button where you can easily disable/enable Javascript.
The 'ev' button that you see in the screenshot at the end of a line shows that an onclick handler is attached.
