drag text from one text filled in one tab to another text filled in another tab

currently when dragging text from one text filled in one tab to another text filled on another tab it wont select the other tab so that i can drag the text to the text filled i want on the other tab. i can only drag text from one tab to the other which overrides the webpage which doesn’t allow me to drop text the text into the text filled i want that exist on the webpage it’s self.

this is really hard to explain. read it over a few times and if you don’t get it i will try and explain it another way.

if you have firefox, open 2 tabs with web pages on them that have a text filled. then try dragging text from one text filled on one tab to the text filled on the other tab. firefox will allow you to do this. now try doing this with comodo dragon. it wont let you because it wont select the other tab when drag text and hover over the other tab.
