I accidentally removed a website from my saved password list. Now when I return to the site and fill in username and password, Firefox has not asked to save password for this site again. How do I get Firefox to prompt to save the password?

The website may be using autocomplete=off to prevent Firefox from saving the name and password.

You can remove autocomplete=off with a bookmarklet to make Firefox save the name and password.

Make sure that there aren't any entries with an empty name in the password manager.

• Tools > Options > Security: Passwords: "Saved Passwords" > "Show Passwords"

Make sure that you do not run Firefox in permanent Private Browsing mode.

this is not help. How I can find my password which already "removed" in firefox? I already put the username in site but password doesn't appear anymore. I already enable "remember password for sites". is it still possible to find it again?

Are there currently any passwords saved for that site?

• Tools > Options > Security: Passwords: "Saved Passwords" > "Show Passwords"

You can also check the about:permissions page to see if there are passwords saved.
You can open about:xxxx pages via the location bar like you open a website.

yes, some others web still saved the password and I can see them. Now, the problem is I accidently remove 1 password. How to find it again?
