437577 - back/forward buttons removed after upgrade

Status: RESOLVED DUPLICATE of bug 426026

(Firefox :: Toolbars and Customization, defect)

Description

[Thomas Lauckner]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; de; rv:1.9) Gecko/2008060519 (Gentoo) Minefield/3.0
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; de; rv:1.9) Gecko/2008060519 (Gentoo) Minefield/3.0

After up- or downgrading from/to firefox-3 (rc2) <-> firefox 2.14, the arrow-buttons for jumping back and forward in the history vanish from the navigation toolbar. They can be added manually, but that should not be the normal behaviour.

Reproducible: I've tested it three times.

Temporary Solution:
The buttons can be added manually by clicking "view"->"toolbars"->"customize"

I've already reported this to https://bugs.gentoo.org/show_bug.cgi?id=224969 and I was told that this is a bug for upstream.

Reproducible: Always

Steps to Reproduce:
Up- or Downgrade from Firefox-2 to Firefox-3 (or vice versa)
Actual Results:  
The Back-Forward buttons vanish.

Expected Results:  
The navigation toolbar does not change.

I think I found a way to the source of the problem:
===
If you "customize" your navigation bar, you see in FF2, that the
Back-/Forward-arrows are two seperate items, while in FF3 they are merged to
one single button.
===

Suggested solution: If FF3 detects an old FF2-profile, it should test if the user has those buttons in his/her toolbar. If existend, they should be converted to the new format.

Thomas, this might be a dupe of bug 426026.

In a way, yes, in a way, no. In my case, the part

"Doubly annoying because they don't
show up in Toolbars>Customize, they get dumped in the (hidden) navigation
toolbar."

is not true. It's also too late since I've reported this as a bug to mozilla (I didn't find the bug you mentioned before *doh*) ;)

Oops, okay, here's mozilla, not gentoo. Forget all of the comment above:

I can't verify the sentence "Doubly annoying because they don't
show up in Toolbars>Customize, they get dumped in the (hidden) navigation
toolbar." because my Navigation toolbar is not hidden. But in all other symptoms, it's a dupe.
