Hi Bill, just making sure I understand your question, you want to import bookmarks to your Chrome from Firefox?

Sorry, I have no import bookmarks feature in Firefox to import from the Chrome Browser into Firefox on either of my Lenovo Chromebooks. From Google Play I downloaded and installed the recommended Firefox and neither will import and neither has the standard library feature in Firefox.

Oh, your device identification looked like you're running the full desktop version, not the mobile/tablet one from Play Store. I don't think the mobile version has any import functionality available unfortunately.

There's a way to run the full dekstop–like Linux version though, see Run Firefox on ChromeOS — however I'm not sure how successful it will be in pulling the builtin Chrome data though, given the system being pretty locked–down…
