In case you use GNOME, you can use this extension to store your
passwords in the GNOME Keyring:
https://github.com/swick/mozilla-gnome-keyring
or easily installable from
https://addons.mozilla.org/En-us/firefox/addon/mozilla-gnome-keyring/
There also seems to be an extension for KDE5, I haven't tried it but
according to the reviews it should work:
https://addons.mozilla.org/en-US/firefox/addon/kde5-wallet-password-integrati/
Unfortunately you will have to fill your passwords in all over again,
but you only have to do that once and then you can use the Firefox
passwords across different profiles and different browsers - as long as
they are based on Firefox and you install the extension, of course.
