Click the Saved Passwords button and then click Show Passwords in the next menu. Delete it in there.

Thanks.

Make sure that you never use a password that can be found via a dictionary look up.

A good way of storing passwords is to use an external password manager called KeePass. It's open source and easy to use: http://keepass.info/

You can load sites directly from the application provided you've stored the site in the profile you create for each one.

Going into TOOLS, then OPTIONS, then SECURITY, and unchecking the two items listed under PASSWORDS seems to have solved the problem. There was not anything listed in SAVED PASSWORDS, but this seems to have resolved the issue anyway. Thanks, KP

I did the Tools, Options, then security and unchecked the last two items. I suppose this means that Firefox won't remember any of my passwords from now on. Does this help reduce hacking? After the Firefox Update this morning to the 13.01.1, my Yahoo email account immediately went into 'hacked mode" and I couldn't send messages as I kept getting kicked out of my account. I changed my password and also my Facebook password, but this doesn't seem to have made a difference so far. I start to type a reply to an email and immediately a box would pop up telling me that my log in had expired and I had to log in again. I sent a complaint report to Yahoo. I've gone this with them before; also with their lousy Messenger that you can't uninstall. But, things had straightened out for two weeks and now this happens this morning. For some reason, it seems most of my internet problems happen on Sundays!!! So, for me the jury is out yet on whether unchecking these options will stop; the hackers from taking over my email account. I sure hope so as I just can't keep up changing email account passwords almost daily!

That's not a hack, that's a bug in Firefox 13. I'm using Firefox 12 until Mozilla can fix it.

Oh, thank you so much for telling me. I was wondering if anyone else has been experiencing this problem. I'm sure it has been reported to Firefox, or at least I hope so!!

You are not alone...

Thank you jcanth. Wow, what a total mess this is. I read through the 3 links above. Could you please also be so kind to point me to the way to go back to Firefox 12 as I don't know how to reverse this and return to Firefox 12.

LindaEllis, if you take a look at this link again

https://support.mozilla.org/en-US/questions/929037

and scroll down to the thirteen and sixteenth posts, they'll tell you where to find Firefox 12 for Windows in Mozilla's archives, and how to install it.

I'm back on Firefox 13.01 and the webmail and Yahoo Home page appear to be sorted.

From another similar problem, I learned that going into Tool/Options - Network Settings, and changing the proxy setting from AutoDetect Proxy to Use System Proxy, or No Proxy gets rid of the password pop-up problem.

I've been using 13.01 for the last 10 minutes or so, with Yahoo as my home page, and I've ended and started FF five or six times, and each time, my it went straight to my homepage without requesting a password. E-mail looks to be working fine as well.

Hi jcanth,

I am still periodically receiving the 999 Yahoo error where I click on it and then I'm okay for awhile. I've written quite a bit to the Yahoo help folks and they are strongly suggesting that I use Google Chrome. I don't have the problem in IE8, however, for me my Yahoo email is extremely slow in IE8 (I use XP). It is a bit better in Firefox but it seems that as the day progresses during the whole week whenever I am using my Yahoo email, over time the "999 Yahoo error" pops up. It can happen at any point including sending a message where I am stopped and then I have to check out of it and then try to send the message and it usually works. Do you have any suggestions for getting rid of the 999 Yahoo error? According to Firefox, they don't want people to revert back to using their 12 version and they want you to do a troubleshoot, and I'm nervous about doing that too. Thank you and thank you for sharing your help with all of us here.

I wouldn't know about that particular problem, as I don't get the 999 Yahoo error. Sorry

Thank you. Maybe your 'fix' for the other problem would also be of help for the 999 Yahoo error as well. Thank you for your quick reply!!
