168050 - New pages sometimes open in wrong tab.

Status: RESOLVED WORKSFORME

(SeaMonkey :: Tabbed Browser, defect)

Description

[Richard Ekle]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.1) Gecko/20020826
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.1) Gecko/20020826

Sometimes when using tabbed browsing, you'll click on a link to open a page and
the page will open on the wrong tab.

Reproducible: Always

Steps to Reproduce:
1. Open two Mozilla Windows
2. On each of the Mozilla windows, open several tabs and load pages.
3. Go to the 2nd or more tab on the 2nd window.
4. Click on a link to open a page.

I would expect that the page should load in the same tab you were on when you
clicked on the link.  In fact nothing appears to happen.  It wasn't until later
that I discovered that clicking on a link on a tab on the 2nd page, opens the
requested page on the first tab of the FIRST window.

any specific pages ?
maybe its a frameset targetting problem ?

[Richard Ekle]

It may be a frameset problem, but I think its a problem in how Mozilla handles
it.  When you have MULTIPLE Mozilla windows open and you do the procedure below
from the SECOND Mozilla window created, the window opens up on the FIRST Mozilla
window created.  Mozilla should be opening the page on the SAME Mozilla window
that the link was clicked on from.

I get this on 1.4b(winXP).  I can't reproduce reliably, but I've had it a couple
of times. I dunno what the appropriate status for
CONFIRMED_BUT_DARN_HARD_TO_REPRODUCE would be :)

I don't think it's related to muliple windows, I can't be so sure for the
frameset hypothesis.  The one test case I got today has one of the three open
tabs having frames.

I've had it today viewing only the following three pages (in 3 tabs in the same
browser window):

http://my.yahoo.com (my linkfarm, nothing special)

http://www.digital-digest.com/dvd/downloads/dvdx.html   (opened via new tab
(from the icon on the tab bar, followed by entering text in address bar, cursor
down, return)

http://www.nature.com (opened from a "open link in a new tab" from context menu
on link on my.yahoo page).

I added three screenshots as attachments, in temporal order:

1. "nature_tab.png".  I've already closed the yahoo page (sorry), but the
   nature.com and the dvdx tabs are open.  Note that the address bar and tab
   titles are correct, but the nature tab's page is empty, its content being
   shown in the dvdx page

2. "dvdx_tab.png".  The same condition as 1, showing the dvdx tab which is
   displaying the nature page

3. "new_tab.png".  After the above condition, I create a new tab (using the
   new tab icon on the tab bar) - the new tab shows the contents of the
   hitherto missing DVDX page

The condition persists until the browser is closed. Clearly it's got some
persistent off-by-one mismapping between tabs and their corresponding pages. 

Theory: race condition w.r.t opening new tabs and the google-search feature of
the address bar ?

unable to reproduce in latest linux builds on fedora core 1 or on windows on xp
or 98

I used to get this very regularly, but I've not had it in a _long_ time, so I'm
confident what ever caused it was fixed many releases ago. Asa's
RESOLVED-WORSFORME seesm entirely appropriate.
