Comment 46 for bug 1228250

Comment on attachment 194913
Backend and all new Frontend (V2)

I tried the patch and noted several things:

- The new controls on the page do not fit the contents of the prefs panel
(clipped in width so that I don't see the arrows of the drop-downs, and I only
see the upper left corner of the Advanced button), even on my system and I know
that on other systems the panel appears even smaller

- The UI is confusing. Why do the options for horizontal scrolling appear in
the box for vertical scrolling as well (and vice versa)?

- What am I supposed to select if I want Ctrl-Scroll to give me horizontal
scrolling? Currently, I cannot get that to work.

I think a different approach is needed. If the user does not have a mouse with
horizontal wheel or an option to switch direction, then the lower half of each
panel is useless. Instead, Mozilla should be able to detect that (difficult to
do that cross-platform, and probably impossible on Linux), hide the lower part
and instead display a check box saying
    [_] Use this modifier to scroll horizontally
or something like that.
