Hi Jscher2000, I logged out, went to security and removed my saved Yahoo passwords, did the IEQ fix (after i hit enter, I put in my password and logged in). But if I then open a new window, I still have to re-enter my password.

Maybe I'm just a hopeless case! Maybe time to wait and see if the next version of Firefox fixes this. Or time to consider switching to gmail (which i've never much liked) Either way, I really appreciate all the help I've gotten here.

Hi jude23, during the login, did Firefox drop down the little dialog allowing you to save your password for Yahoo?

If it did, and you allowed it, then there must be some other problem different from the other posters, something that is making Yahoo suspicious of your browser for some reason.

If the problem is particular to separate windows -- i.e., if you set your tab options to divert new windows to new tabs in the same window then it works -- perhaps one or both of the windows are "private" windows? I think starting in Firefox 20 with the introduction of per-window-private-browsing those windows might not be able to share the same Yahoo! session, but I haven't experimented with it.

Jscher2000, I can see that the new password is saved because I previously deleted it from the list of saved passwords, and it is back again.

I shouldn't have said that about separate windows--because while I have to re-enter the password if I open a new window, I also have to re-enter if I simply return to Yahoo on the same window. Besides, none of my windows are private because passwords for all other sites are remembered just fine.

Gosh, there must be other folks out there with this problem!

Hi jude23, I had forgotten that you said it works correctly in Firefox's Safe Mode -- way back two pages ago. I think the next thing to investigate is whether any of your extensions might be blocking one or more of your Yahoo cookies, or filtering other information expected by the Yahoo server, or blocking content from Yahoo-related servers. Anything related to privacy or ad/content blocking would be worth a close look.

Jscher2000, turning off all my extensions and add-ons is another thing I did before coming here. And that didn't work. The only thing I can think is that I didn't do a restart after disabling them, but I don't think that should have made a difference(?)

Hi jude23, when you disable an extension, if Firefox needs to be restarted in order for that to take effect, a link will appear above the extension to restart with a single click. Anyway, it's easy enough to visit the extensions list and see their status.

Jscher2000, yeah, so extensions seems to yet another dead end for me...

Bless your heart! Have you considered just doing a clean reinstall of Firefox and starting over? Then doing the "Inspect Element" thing? Worked for me.

sherylsr, oh I thought you reported earlier that the reinstall did not work, it only was fixed when you did the IE(Q). But you're suggesting the combination might be what did it? Well, yeah, I'm at the desperate stage (!) might as well try anything. I'll set aside time this weekend...

I'm wondering if a clean reinstall in addition to the "Inspect Element" would work. Sounds like you've been doing a lot of tweaking here and there trying to get this bug fixed. That's why I'm wondering if starting over, so to speak, would help. Did for me. Because I did a lot of messing around beforehand with Preferences etc before I found this discussion. Now have my life back! :-)

[Fingers CROSSED!]

A few days after my original post, I typed in my username and the password appeared. This is different from the usual behavior where both the username and the password was inputted... which is fine on my home computer. This was using that little scriptlet to make sure Firefox actually asked to save it.

In Firefox Safe mode these changes are effective:

• all extensions are disabled
• the default theme is used (no persona)
• userChrome.css and userContent.css are ignored
• the default toolbar layout is used (localstore-safe.rdf)
• the Javascript JIT compiler is disabled
• hardware acceleration is disabled

• plugins are not affected
• preferences are not affected

• https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

Create a new profile as a test to check if your current profile is causing the problems.

See "Creating a profile":

• https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
• http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.

Well, everyone, back to say that I did a total reinstall of Firefox, and then did the IE(Q) fix, and .... problem is still here! :-(

Hi jude23, since the posts are spread out over a couple pages now, I'll summarize the troubleshooting so far, and please correct as needed:

• Firefox stored your Yahoo login successfully and Firefox will log you in the first time (so the Inspect Element trick isn't needed at this point)
• In normal mode, Yahoo keeps asking you to confirm your password when you navigate to a new page, or even if you reload the same page
• Deleting Yahoo cookies didn't resolve it
• Renaming cookies.sqlite didn't resolve it
• In Safe Mode, you can navigate normally on Yahoo
• Disabling extensions does not resolve the issue
• Setting No Proxy in connection settings does not resolve the issue

It seems to me that for some reason Yahoo is not trusting your connection. Usually this would be due to cookie issues or changing IP address issues, or an extension, but you've ruled all of those out. And other browsers are not affected.

You mentioned running Windows on a Mac. Are you having this problem in the native Mac version of Firefox or in the Windows version?

One of the other change made by Safe Mode is disabling the use of hardware acceleration for graphics. While it is hard to see what this could possibly have to do with this problem, you may want to try it anyway.

You usually need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).

(MAC) Firefox menu > Preferences > Advanced
(WIN) orange Firefox button (or Tools menu) > Options > Advanced

On the "General" mini-tab, uncheck the box for "Use hardware acceleration when available". Then exit and restart Firefox.

Hi Jscher2000

Thank you for still considering this! Yes, your summary is correct. And I just tried unchecking the acceleration, with no effect.

I run Windows via bootcamp, but can't tell you the last time I even went to the Mac side. I have used Yahoo mail on Firefox for 10+ years with no problem, and on this computer for over a year, with no problem till about a month ago. I'm trying to think what coincided with the start of the issue, but nothing comes to mind. Possibly there was an update around that time?

thanks again!

Did you try to reset all preferences?

Rename or delete the prefs.js file and possible numbered prefs-##.js files and a possible user.js file to reset all prefs to the default value.

Thanks for everyone's response. I have tried most - if no all - of these suggestions. However, the reality is that this is a Yahoo problem - not a Firefox one. Yahoo, have simply swtiched off the ability to save usernames and passwords (like banks do) on the browser. They have done this without informing their customers. The silly thing is that Yahoo Customer Service Team have no idea about it - they are totally in the dark (or clueless). I have been in email communication with them for the past two weeks and they still have no idea about the issue. Clearly some boffin(s) in a glass room thought that making this change was 'good' but didn't think about the users. I suspect they just want it to go away. The are being totally dismissive of their customers. All I can say is hello gmail and/or outlook.

Thanks, cor-el, for the suggestion about preferences. I haven't had a chance to look into that. But I was under the impression that my preferences were all reset when I did a complete reinstall of Firefox.

Mari123, glad to hear you had some conversations with Yahoo. I got nowhere with them, either.

I wanted to say, too, that this issue is wonkier than just Yahoo turning off the ability to save usernames and passwords. In my case at least, my username remains saved, and I don't think Yahoo has actually signed me out in weeks(!) At the same time, the password is forgotten, but (probably since reinstalling Firefox), now when I open the browser to my homepage, which is set to Yahoo mail, I do NOT need to enter my password. And I can refresh that page okay. BUT if I click on the bookmark to my email page or if I open another window (tab), it wants a password again. Bottom line, this is not a straightforward issue.

Hi guys, Hi cor-el, Jscher, and everybody!

I SOLVED it!!!!!! (and by myself, no less :-) )

Guess what, by chance, while looking for something else, I saw that SSL was checked. [i.e., "Make your Yahoo! Mail more secure with SSL (i.e. preventing others from accessing your account at Internet cafes)] I unchecked it, presto, problem solved. Holy smokes!! I think this is the 60th post on this thread. No one is probably reading anymore...

What is weird though, is why this problem started a few weeks ago. It's not like I went in and checked SSL.

Anyway, I'm just glad to have an answer. And hope by posting it here that it helps someone else down the line.

And again thank you to everyone who went way beyond the 'call of duty' to over helpful suggestions!
