Zotero not communicating from Word with Comodo Icedragon

Hi, I replaced my Firefox browser with Comodo Icedragon. I installed the reference management software Zotero add-in in MS-Word, but it is not communicating with the Comodo browser (with the necessary Zotero add-ons).

Anyone suggestions? ( -P -no-remote does not do the trick)

(B.t.w from MS-Word it can connect to a portable Firefox (at my memstick)).

Thanks.
Richard
