is there a way of making it work with CoolPreviews?

Can you be more specific about what does not work? I tried CoolPreviews 2.7.6.0623 (https://addons.mozilla.org/en-US/firefox/addon/2207) and Link Status works fine with it. In addition, judging from the source code, I cannot see any potential reason they might conflict.
