424110 - Some visited links stop being shown in magenta

Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[Chris Lowe]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b4) Gecko/2008030714 Firefox/3.0b4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b4) Gecko/2008030714 Firefox/3.0b4

I have an intranet system that presents lots URLs on pages.  The list of URLs appears in one frame, the result of the URL is in another.  There's some javascript, too.

<a href="/B-40999" target="bug" onclick="highlight('B-40999',0);current_rowid='B-40999-1';return CheckFrame(this);" class="bugid">B-40999</a>

First time I click on such a link, the link changes colour.  But after I've refreshed the page, a large portion (90%) of the links revert back to blue.

Sometimes it takes 2 refreshes for the link to revert back to blue.  It appears that visiting similar-looking links (say href='/B-40999' and href='/B-30385') cause the memory of the visit to be lost.


Reproducible: Sometimes

Steps to Reproduce:
1. Visit a page containing a link like <a href="/B-40999" target="bug" onclick="highlight('B-40999',0);current_rowid='B-40999-1';return CheckFrame(this);" class="bugid">B-40999</a>
1a.  Note, link goes magenta.
2. refresh the page containing the link
3. See link go back to Blue.





This bug afflicts FireFox 3 Beta 4 (and Beta 3 before it).  It does not affect Firefox 2.

Attachment: TESTCASE (frameset)

This is a testcase that would demonstrate the bug.

Unfortunately, it does not appear to trigger the bug when used on bugzilla.mozilla.org. However, I was able to reproduce the bug with these files stored locally in a single directory. If you download the files and change the links in the HTML accordingly, you may be able to reproduce it too.

STEPS TO REPRODUCE:

* Download the four attached files locally (name them whatever you like)
* Change the links inside the HTML accordingly
* Keep clicking on the "Page 1"/"Page 2" links in the left frame. They turn purple
* Reload the entire frameset, possibly multiple times.

ACTUAL BEHAVIOUR:
One of the links (or both) turns blue eventually. (It may require 20-30 reloads.)

EXPECTED BEHAVIOUR:
The links should remain purple until the URL is expunged from the browsing history.

Bug 428719 looks to be similar.

Tried this in FF3RC1, and the problem appears to be fixed.

Comment 9

Well, not quite.  There's a corner case where you click on a link, it turns 'visited', then before the linked page completes its load in the other frame, you click on another link.  Next time you reload the frame with the links, those pages that didn't complete are still shown unvisited.

But I can see that this is reasonable behaviour.
