Question

Firefox extension does not honor "fill only on exact host"

I have a login saved for `https://grafana.foo.bar.mydomain.net` with “Only fill on this exact host” selected.

However, when I’m on  `https://whatever.something.mydomain.net`, this login is also offered.

 

Maybe related: Recently I noticed that adding a “Never fill on this website” URL to an entry is not honored either.

OK, somehow it fixed itself. Weird. Still curious about  “Never fill on this website”  not working properly though.

Hi ​@ThiefMaster thanks for reaching out.

 

I’m glad that you’re no longer having issues with the “Only fill on this exact host” autofill behaviour.

 

As for your issue with the “Never fill on this website” behaviour, I have some questions to help me better understand what's going wrong and so I can provide the best advice moving forward.

 

  1. Can you confirm what device this is occurring with?
  2. Does the issue occur with multiple items you have, or just a specific one?
  3. Do you have multiple website fields with autofill behaviours configured in your affected item(s)?

 

Let me know if you have any questions.
