Website link?

I tried several sources eg C-Net, and Cool Iris www.cooliris.com or https://addons.mozilla.org/en-us/firefox/user/the-cooliris-team/

I don't see any information related to Cooliris and Firefox compatibility at www.cooliris.com and the second link, https://addons.mozilla.org/en-us/firefox/user/the-cooliris-team/ is a user page for the add-on developer(The Cooliris Team) and only mentions one add-on, [https://addons.mozilla.org/en-us/firefox/addon/coolpreviews/ CoolPreviews]. If you are downloading Cooliris from another site and it gives you an error that your Firefox version is not compatible, it's likely that you have downloaded an outdated add-on that was made for an older Firefox version. In any case, your best bet would be to contact the add-on developer.
