I really recommend switching to a password manager - it's also easier to access the passwords from other devices. For example I can use the same passwords on Firefox desktop and on Safari - iPhone (including auto-fill on iOS 12). I have good experience with 1Password (subscription paid).
You should use a password manager, there's been a few cases already where malware shows how trivial it is to steal and decrypt into plain-text passwords stored by the browser.
Unless you have adversaries personally attacking you, your main threat is automated malware. In that case, I think that it's vastly more likely that said malware would target super-popular and totally-insecure software like the Chrome password manager, rather than something not very popular and quite secure like KeePassXC.
I personally recommend Bitwarden as a good compromise between security and usability. It's totally open source, so you can run the API and webservice on your own hardware if you want.
