When I attempt to log-on to Firefox, I get a pop-up box telling me "We noticed you may have signed in or signed out in another window. Click OK to reload your page. How do I fix this?

After I click OK to reload my page, it reloads but it doesn't load to my home page which is www.my.yahoo.com.

Firefox cautions against going to the lengthy trouble of using Safe Mode. Instead, it recommends resetting the browser to its original default settings. On 06/10/2012 the recommendation worked correctly for me. I have opened Firefox a few times and not endured a repetition of the message, "We noticed you may have signed in or signed out in another window. Click OK to reload your page." It takes a matter of seconds:
Click Help

Click Reset Firefox

Why do I keep getting a warning "We noticed you may have signed in or signed out in another window. Click OK to reload your page." Annoying message?

Each time I go back to my.yahoo.com, why does it keep getting a warning "We noticed you may have signed in or signed out in another window. Click OK to reload your page." message?

How about the cookies for that domain - did you delete those cookies?
"Keep me logged in for ..... weeks/days" is usually done via setting a cookie in the browser so the website recognizes the browser when you return and automatically logs the user in to the website via that cookie.
It seems that some websites have a problem recognizing the "remember me" cookie after a Firefox update, and the user need to set a new cookie with the updated version of Firefox so the website will recognize your preference. This particular problem with some websites not recognizing their own "remember me" cookie started like 4 years ago, shortly after Firefox 3.0 was released with an all new method of storing cookies. In the last 4 years this problem is mentioned less often as the years went by, so some websites must have fixed it at their end - where other websites evidently haven't gotten a handle on it.
Websites really need to get involved in the various "programs" out there like Browser ID / Persona - https://login.persona.org/about - and get rid of that hokey "cookies" method of remembering the users preference for being automaticall logged in upon their return to their website.

I get this message everytime I start Firefox..."We noticed you may have signed in or signed out in another window. Click OK to reload your page." How do I get rid of this?

Every time I'm finished with the internet, I close/exit out of Firefox, but every time I sign into Firefox, I get that annoying message telling me I have signed in or out of another message. What causes this and HOW DO I GET RID OF IT?
Thank you for any help.
I have contacted ATT DSL service, and they told me it must be my browser.

We notice you may have signed in or signedout in another window. click to ok to reload your page

every time after I click on the firefox icon

I couldn't take it anymore! I cleaned my registry, ran another Firefox update, disabled my add-ons, and went to att.net and att.com to see if they had upgrades to my home page (they didn't). Still that annoying message! As long as I was able to navigate away from my home page, I did not get that annoying pop-up so I decided to get a new home page. I was using att.net/yahoo, and now I am using just yahoo. So far so good - no pop ups. Still would like to know why this was happening-something to do with the att homepage?

When I launch Firefox 4.0.1 I get an error message that says "We noticed your may have signed inor signed out in another window. Click Ok to reload your page." I have to sign in with my username and password. Richard

When I launch Firefox 4.0.1 I get an error message that says "We noticed your may have signed inor signed out in another window. Click Ok to reload your page." I deleted Firefox and reloaded it - did not solve the problem. This started occurring after I downloaded Windows Service Pack 2. I have Vista 7 OS. So every time I close and relaunch Firefox, I have to sign in with my username and password. Very very, annoying. If I can't get this corrected, I have to start using another Browser. Thanks for your help. Richard

It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
Delete the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
* Help > Troubleshooting Information > Profile Directory: Open Containing Folder
* http://kb.mozillazine.org/Profile_folder_-_Firefox
* http://kb.mozillazine.org/sessionstore.js
If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.<br />
Deleting sessionstore.js will cause App Tabs and Tab Groups to get lost, so you will have to create them again (make a note).
