Did Quantum became worse or you're basically saying Mozilla is bad at marketing (and having huge vertically integrated ecosystem)?
I ended up going back for a bit and added a password manager, and now I can move between browsers easily - but as I said, it's not always straightforward, especially for _most_ non-tech users.
I find it rather easy, at least in my case. Passwords are all managed via a password manager, I barely use bookmarks, so most of the work is re-installing and configuring a few plugins, which I also don't use many of
Chrome Settings > Passwords > "Export passwords..." (under the three-dots menu).
Not sure when you last checked but the option has been available since at least Chrome 66, which was released almost two years ago: https://www.ghacks.net/2018/04/18/google-chrome-66-password-...
I distinctly recall the option to manually import passwords being harder to find (solution is to either import them from another browser or enable a flag to import passwords from a CSV file).
Ironically Firefox currently still lacks the native ability to manually export passwords, relying on add-ons or third-party tools: https://www.nytimes.com/2018/07/20/technology/personaltech/f...
