Status: RESOLVED INCOMPLETE

(Firefox :: General, defect)

Description

[Vicki Violette]

User-Agent:       Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.0.04506)
Build Identifier: Mozilla/3.0.1

Previously myyahoo.com was my homepage and upon opening up Mozilla I would be automatically signed into myyahoo.com (no sign in link appeared)  Shortly after updating to the newest Firefox version (3.0.1) when I go online using Firefox, the general yahoo page comes up with the link asking for me to sign in. The first few times this happened I was able to sign in and my personal yahoo page came right up.   Now, when I try to log on, the log in box comes up as if I had not typed anything in it.  This is the same when I try to access my yahoo mail using Firefox.   There is no problem with my yahoo account as I am able to access it using Internet Explorer.  Because of the difficulty accessing yahoo I changed my home page to Google and that worked fine for a few times, but now I cannot access my gmail from my google page.  The same thing happens that happened with my yahoo page:  I click on the link to sign into my gmail account from my google homepage to retrieve my mail and I encounter the same scenerio as yahoo; Everytime I sign in, the sign in box keeps reappearing asking me to sign in instead of redirecting me to my gmail site - it is like being caught in a loop where everythime you try to log in, the log in box just keeps coming up empty.   I have tried to access this info using Internet Explorer and have no problem.  I really like Mozilla but if I cannot access these important pages, I will have to go back to using internet explorer.

Reproducible: Always

Steps to Reproduce:
1.Open up my Yahoo home page through Mozilla
2.Click on the log in link
3.Fill in my username and password
Actual Results:  
I click on the log in link, the log in box appears and I fill in my username and password and click enter.  Instead of now opening my personal yahoo page, the log in box reappears without my username and password filled in.  I repeat the sign in procedure, but again, instead of redirecting me to my yahoo page, the sign in box reappears.

Expected Results:  
I should have been redirected to my yahoo.com

When this problem first began happening with myyahoo.com, although I was not automaticallty signed into myyahoo.com, I was able to sign in using the sign in link. But within a few days not only did my yahoo page not come up automatically, but when I tried to log in I was unsucessful.  After changing my home page to Google.com I was able to access my mail without signing in.  Now, it asks me sign in, but after I try the loop of the sign in box reappearing begins.  This problem is not affected by what theme or lack of that I am using.  It happens everytime with yahoo and google.

I've also had this problem with all Versions 3.x of FF, including the latest version.  I reinstalled Fire Fox 2.0.0.18 and did not have the problem anymore. I found some things that may shed some light on this issue:

1/ By removing the Yahoo.com folder from FF 3.x cookie list I could sign-in to my "mail.yahoo.com" secure home page without the endless sign-in loop. However, if I closed and relaunched FF, the sign-in loop was back in business and the Yahoo.com cookie folder had reappeared. 

2/ I later found, after expanding the Yahoo.com cookie folder and removing various cookies one by one, that the Yahoo cookie named "T" was the culprit; i.e., clearing only that one Yahoo cookie enabled me to sign-in with no looping for that FF session only.

Hope this helps, because Fire Fox is a GREAT product!

No reply, INCOMPLETE. Please retest with Firefox 4 or later and a new profile (http://support.mozilla.com/kb/Managing+profiles). Also, ensure you have the most up to date graphics drivers, operating system updates, and plugin versions (flash, java, etc). If you continue to see this issue with the newest Firefox and a new profile, then please comment on this bug.

I no longer have the problem since updating to later versions of Firefox, specifically Firefox 4.x through Firefox 6.x
