203586 - you can't directly unblock cookies from a site that has endless redirect problems

Status: RESOLVED DUPLICATE of bug 192176

(Core :: Networking: Cookies, defect)

Description

[skierpage]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.3) Gecko/20030312
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.3) Gecko/20030312

If I block cookies from http://www.okmozart.com and "Remember this decision", it
redirects over and over until Mozilla puts up an alert saying "Redirect limit
for this URL exceeded... may be caused by cookies".

BUG: After I dismiss that alert, even though the location bar has
http://www.okmozart.com in it, Tools > Cookie Manager > Block Cookies from this
Site is not enabled.  Either it should work or the UI is misleading.


Reproducible: Always

Steps to Reproduce:
1.  Set your preferences to Prompt for Cookies.
2.  Remove cookie (if any) for www.okmozart.com
3.  Go to http://www.okmozart.com.
4.  When it prompts to allow cookies, click No and check "Remember this Decision"
5.  The status bar flickers between "Connecting..." and "Waiting..."
6.  Eventually you get the alert
"Redirection limit for this URL exceeded. Unable to load the requested page. 
This may be caused by cookies that are blocked."
(Awesome alert by the way!)

7.  Dismiss the Alert
8.  Try to fix the problem with Tools > Cookie Manager > Unblock Cookies from
this Site.
Actual Results:  
Tools > Cookie Manager > Unblock Cookies from this Site is not enabled.  (In
fact, Block Cookies from this Site remains enabled, even though I've already
blocked them!)

There's no way to unblock cookies except by going to Manage Stored Cookies.

If I do this operation in tabs, if I go to another tab and return, the location
field has "about: blank" in it, which is odd but at least indicates that
"http://www.okmozart.com" has not loaded and isn't subject to "This Site"
operations.  (My Mozilla preference is to open windows with a blank page.)

Expected Results:  
It's odd that I can't immediately do what the alert suggested I do!

Perhaps Mozilla won't let you perform "This Site" operations unless it's
successfully loaded a URL.  But from the current UI that's WAYYY too subtle. 
Mozilla tried, failed, even tells me how to fix the problem, the URL is right in
front of me, why can't I operate on "This site"?  If you can't allow the
behavior, perhaps there's some way to indicate that the URL in the location bar
is pending and hasn't become "This site" yet.  (I think the whole notion of
"This site" vs. the location field may be problematic, but I'll leave this bug
under the feature where I first noticed it.)

Confirming.
This is a quite subtle bug, but I ama fraid it is not easy to fix. Indeed, when
no uri is loaded, there is no "this site".

This is a good testcase for 192176, which is about the only way we can fix this
properly.  Now, to perhaps get off my duff and finish implementing it! :)
