Comcast isn't a browser as far as I know, but it is an ISP, (Internet Service provider).
If you are using an AOL browser, then the general way to transfer it's Favorites is to Export them. I can't tell you how to do that as I don't use the AOL browser, but you might find the Export function in the Favorite menu options.
Then, in your new browser, whichever it is, Import that exported file.
Any information please
