214905 - back to previous group of tabs conflicts with page history navigation

Status: RESOLVED INVALID

(SeaMonkey :: Tabbed Browser, defect)

Description

[Gert-Jan Vons]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5b) Gecko/20030802
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5b) Gecko/20030802

After opening a bookmark group, Mozilla now replaces the current set of tabs
instead of just adding them, and the back button brings back the previous group.

However, if after opening the bookmark group, I click on a webpage link in one
of the tabs, I can no longer go back to the previous group: for the current tab,
the back button now takes me back to the previous page, and the "Group of Tabs"
is no longer available. Moving to one of the other tabs doesn't help, the "back"
button is now grayed out.

Reproducible: Always

Steps to Reproduce:
1. open a group of bookmarks
2. click on a link on one of the loaded pages (don't control-click: make it open
in the same tab, _not_ a new one!)


Actual Results:  
Can no longer use the back button to go back to the previous "Group of Tabs",
causing data loss.

Expected Results:  
Not sure what to expect: with the changed behavior related to the opening of
groupmarks (see bug 209360), a concept of tab-set history is introduced, and
mixed with the existing page-history navigation. For this to work right, the
tab-set history should probably be managed by a separate button or something.

Oops, the bugid I referred to should be 203960 instead of 209360...

This is by design and after a lengthy discussion this was chosen as the default
behavior. However the PREFERENCES panel offers a way to switch back to the old
behavior:
PREFERENCES - NAVIGATOR - TABBED BROWSING.

Marking INVALID
