Make sure you are not using Private Browsing.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All of them.

Hi Fred,

Thanks for the suggestion, but unfortunately it did not solve the problem. I went to tools-add 0n, and disabled all, but the save password option is still grayed out . I also made sure I am not using private browsing.

I was once able to save passwords, but added a master password.  When I discovered that passwords could not be saved anymore, I removed the master password, but from then on the save password option has been gray.

hello, firefox won't save your passwords when you've set it up to "never remember history" in the options > privacy panel (a.k.a. permanent private browsing mode).

Settings for privacy, browsing history and do-not-track

Start Firefox in Safe Mode {web link} Then check the password setting.

Did you disable XFINITY ?
