Solved: Chrome does not store passwords anymore
For some reason my Chrome did not autofill stored passwords anymore.
The list of stored passwords was empty and even when I saved a new password, the next time it would not be autofilled.
Problem: maybe the local database broke.
Solution: Force to reload the list from the Cloud by removing the local database.
Under Linux that is:
cd ~/.config/google-chrome/Default mv ./Login\ Data-journal ./Login\ Data-journal.bak mv ./Login\ Data ./Login\ Data.bak
