The issue is probably the plug ins

Try it with IE (Safe mode) as this will be a different browser with no plugins. If the issue doesn't persists (which I assume it won't) then you need to uninstall all pugins in Firefox and maybe even re-install firefox.

The only way to know which plug in was the issue is to remove them one at a time, and re-test, starting with the 'least' known/trustworthy

Because of what the plug in is doing, essentially manipulating the DOM in the HTML page I don't think the AV programs would detect it, especially because you've (accidenlty or not) installed the plug in.

Please note, uninstall is not the same as disable. I've had issues with plugins persists even when disabled.

Clicking the link could will potentially cause issues but just having a link can't damage your PC.
