"Never for this website" not remembered

Bitwarden doesn’t ever seem to remember when I click “never for this website” when prompting for passwords; every time I return to that website, it prompts me again. Any ideas why it might not remember? (Firefox)

Sounds like a bug. For now, you should be able to get round this by changing the match detection for the website in question to “Never”.

This happens for all websites I visit, not just a single one. Any thoughts on that?
