309345 - DP/1.5b1 - IntelliPoint Mouse with horizontal scrolling stopped being able to trigger Back and Forward after upgrade

Status: RESOLVED INVALID

(Firefox :: General, defect)

Description

[Alan Ogilvie]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8b4) Gecko/20050908 Firefox/1.4
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8b4) Gecko/20050908 Firefox/1.4

OS X 10.4 + USB Microsoft Optical Wireless Mouse 2.0

Installed Firefox 1.5b1 (DP) over 1.0.6 release.

The Mouse has horizontal scrolling on a tilting mouse wheel. With previous
Firefox releases the horizontal scrolling feature mapped to Back and Forward
navigation. Once copying the 1.5b1 package over 1.0.6 and running it this
stopped working.
Looking through all the preferences within Firefox and the System Preference of
Mac OS X and the IntelliPoint driver I can't see of any way of correcting this.

Reproducible: Didn't try

Steps to Reproduce:
Not sure how to reproduce this reliably - as now my profile has been updated to
1.5. If I was testing this properly, I'd have kept a copy of my profile and done
it all again.

1. Install 1.5b1 over 1.0.6
2. Start Firefox 1.5b1
3. Browser to a few sites, see if you can use the horizontal scrolling feature
of your mouse to go 'Back' and 'Forward'.

Actual Results:  
Couldn't go back or forward.

Expected Results:  
Navigated back or forward (scroll left = back, scroll right = forward)

Ok - a little more information.

It seems that by preferences were being reset by the installation.

mousewheel.horizscroll.withnokey.action was changed from 2 to 0

and...

mousewheel.horizscroll.withaltkey.action was set to 2

It would be really good if there was documentation that I could find on the
Mozilla site about these preferences. I had to search google and piece together
from other people's stories.

I'm leaving this bug open, in the hope that this is taken on board about the
preferences.

This was intentional.  The horizontal scroll wheel on the Mac is supposed to
scroll the document horizontally and not do history traversal.

Shift+vertical scroll is supposed to do history, but scroll wheel modifiers are
broken on the Mac at the moment, and shift is a bad scroll wheel modifier to use
on the Mac.  That's bug 171680.  When that and bug 309227 are fixed, there will
be a modifier that lets you do history traversal with a scroll wheel on the Mac
by default.
