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.
