541263 - Tracking present in yahoo favicon

Status: RESOLVED INCOMPLETE

(Firefox :: General, defect)

Description

[yachtracers]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.7) Gecko/20091221 Firefox/3.5.7
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.7) Gecko/20091221 Firefox/3.5.7

Yahoo appears to have gotten around the previous fix preventing tracking
through use of the favicon. I am running XP Pro, XP, and Linux, in addition to
NoScript, and I have the issue on all machines. going to yahoo logging in and
checking mail, logging out (NO scripts allowed during process) then visiting
another site will reproduce the issue. If I clear private data after logout,
the problem will not occur. This is not a global issue (of the 15 favicons I
have) but limited to yahoo. I have experimented with adding other "suspect"
sites and none of them has done it either.

Reproducible: Always

Steps to Reproduce:
1. Visit yahoo
2. Go to another site
3. Leave site and return to yahoo.
Actual Results:  
Yahoo favicon is that of other site visited until private data is cleared

Expected Results:  
yahoo favicon is that of other site

Nothing.

I cannot confirm the behavior you are seeing.  I followed your steps to reproduce and I see the correct favicon on each of the successive sites I visited.

Is it possible that you have an add-on installed that is misbehaving?  Try running in safe mode and see if you get the same behavior:

Reporter, are you still seeing this issue with Firefox 3.6.13 or later in safe mode or a fresh profile? If not, please close. These links can help you in your testing.

Also, ensure you update all your plugins (Flash, Reader, java, quicktime, etc) to the latest version available on the vendor's website.

Works for me, Firefox 20110309 3.5.18pre on Linux, with NoScript 2.0.9.8
and no other add-ons.

[e-mail], please reopen this bug report if you can reproduce
it in Firefox 3.6.15 or newer.
