Quick summary: I want Firefox to remember and autofill usernames, but not save passwords.

Since a lot of web sites use email addresses as usernames and I regularly use a disposable email address service, I have a lot of different usernames on a lot of different web sites, and they are impossible to remember.

I would like Firefox to remember and autofill the username I use on each site, but I don't really want it to remember my passwords. I just really dislike the idea of a computer remembering my passwords for me, plus if I get in the habit of that, I'm more likely to forget them and be unable to log in from anywhere but my accounts, whereas I don't mind a computer remembering my usernames and email addresses.

The default Firefox "Remember search and form history" doesn't meet my criteria because it will present data as suggestions that I've entered on other web sites, and my DEAs are random collections of numbers and letters. I wouldn't have to remember random strings of characters, but I would have to remember which random string is which, and there's only marginal benefit to that.

Does anyone have any suggestions? An extension seems like an appropriate solution, but I'm open to anything faster than what I'm doing now, which is to log into my DEA service and search for the email address.

You should look at the add-on lastpass.

This keeps all your passwords online and encrypted so only you can access them. However, they're accessible anywhere in the world.
It has too much functionality to detail here, but is quite complete regarding features.
Available for Windows, Mac and Linux, in my experience it's the best password manager.

I checked this out. It does look nice. And you can get it to not store passwords. Or, rather, you can delete them after you store them the first time. (I suppose I could set up sites manually.) But, for whatever reason, if there's no password, it refuses to autofill. I think I might submit them a bug report/feature request. – wfaulk Sep 28 '09 at 17:45
After the form is submitted, lastpass asks whether to store the pw, not now, or never. If you wish an add-on that remembers all form fields, you can also use "Lazarus: Form Recovery" at I use them both. – harrymc Sep 28 '09 at 18:04
Yes, but if you say not to save the password, it doesn't save anything. Again, I want to remember the username (and potentially other non-secure fields) but just not the password itself. I didn't specify that I want it to automatically fill out the part of the form that it knows, which disqualifies Lazarus. I'll edit the question for that. – wfaulk Sep 28 '09 at 18:24
Lazarus does what you want. I've added it as a separate answer. – harrymc Sep 28 '09 at 18:34
I'm going to work with them and see if they can't get this issue fixed. They already emailed me back with information that implied they expected it to work the way I want already. – wfaulk Oct 1 '09 at 20:25

Found here:

Firefox will remember passwords by default. You may have disabled this feature, or told Firefox to never remember passwords for a particular site.

  1. At the top of the Firefox windowOn the menu bar, click on the ToolsFirefoxEdit menu, and select Options...Preferences....
  2. Select the Security panel.
  3. If it isn't already check marked, check Remember passwords for sites.
  4. To the right of Remember passwords for sites, click the Exceptions... button .
  5. Make sure that the site you're trying to log in to isn't in the list. * If it is, select the entry and click Remove.
  6. Click Close to close the Exceptions window.
  7. Click OK to close the Options windowClick Close to close the Preferences windowClose the Preferences window

This disables saving passwords and usernames, doesn't it? This is one of the first things I do with a new Firefox installation. I suppose it's possible that I disabled something else that caused the usernames to also not be saved, but I don't think so. – wfaulk Sep 28 '09 at 18:18
No, it doesn't. Just start typing your username in the usual place and you'll see the complete username just below the field. It can be autocompleted with Tab. Or just press Alt-Down without typing anything and select the name – user7963 Sep 29 '09 at 14:21
Whoops. You're right. The other thing I disabled was "Remember search and form history" on the Privacy tab. But it still doesn't solve the problem, as Firefox doesn't distinguish between forms very well. I'm not sure what criteria are used, but I can have (and, in tests, did have) Firefox suggest things filled out in one form in a completely unrelated form. So it doesn't really solve my problem. – wfaulk Sep 29 '09 at 18:15

You should look at the form saver add-on "Lazarus: Form Recovery".

By default it doesn't save passwords, but it saves all the other fields in the form:

Yep, does what I want, except I still can't find the part where it does it automatically. That is, without me pressing any buttons. I doubt that that feature is there, honestly, as you don't want your forum post filled in every time, and that's what this extension is really for. – wfaulk Sep 28 '09 at 19:13
To be clear, I do say that anything faster that what I'm doing now is sufficient, and both Lazarus and LastPass fulfill that requirement, but I'm hoping that something that meets all my criteria will come along. I'm not trying to be overly negative. – wfaulk Sep 28 '09 at 19:16
