    Firefox - Arrows disappeared from scrollbar

    Since upgrade to Firefox 46 I no longer have the 'up' 'down' arrows on the scrollbar.

    I have had a good look around and there is a mention of a change to gtk-3.0 by Firefox.

    I am a relative novice and havn't got a clue what this means.

    Can someone please explain how to get my arrows back or advise on how to revert back to FF45

    Thanks

    It's not really a good idea to drop back a version for something like that!

    You can still scroll up or down with the up and down arrows of your keyboard or page up or down!

    Anyway, you could try editing the gtk-widgets.css file of your gtk3 theme to change
    Code:
        -GtkScrollbar-has-backward-stepper: false;
        -GtkScrollbar-has-forward-stepper: false;
    to
    Code:
        -GtkScrollbar-has-backward-stepper: true;
        -GtkScrollbar-has-forward-stepper: true;
    This, of course, assumes that your theme supports arrows in scrollbars.

    On an unrelated note, you may also want to edit ~/.config/gtk3/settings.ini to include
    Code:
    gtk-primary-button-warps-slider=false
    to enable legacy scrolling.

    Hi
    Thanks for the reply. (sorry for the delay in responding)

    I have previously enabled legacy scrolling.

    The problem that I have is that can't find the gtk-widgets.css file

    I always use the mouse wheel for scrolling, I think that's what most people do and maybe the reason for removing the arrows.

    Could you mention which theme you're using and where it's located? Is it in /usr/share/themes or ~/.themes or ~/.local/themes?

    As I say, I am a linux novice. But, have used Ubuntu 14.04 as it came (out of the box) for 2 years. Its been fantastic but I am not sure what theme it uses.

    In that case, you'll have to wait until a Ubuntu 14.04 user comes along.

    If you have never changed themes, it's possible you're using Ambiance and that's in /usr/share/themes. The file that needs to be modified would then be /usr/share/themes/Ambiance/gtk-3.0/gtk-widgets.css. To modify that file, you'll need elevated privileges.

    The relevant section seems to be:
    Code:
    /*************
     * scrollbar *
     *************/
    .scrollbar {
        -GtkScrollbar-has-backward-stepper: 0;
        -GtkScrollbar-has-forward-stepper: 0;
        -GtkScrollbar-trough-border: 0;
        -GtkScrollbar-min-slider-length: 31;
        -GtkRange-slider-width: 10;
    
        background-color: @scrollbar_track_color;
        background-image: none;
        background-size: 0;
        border: none;
        border-radius: 0;
    }
    in which you'll need to change 0 to 1 for the backward and forward steppers.

    If you are unsure, I suggest you leave things as they are and just live without the arrows. They really aren't necessary. Several themes have dropped them. I've never used them, even when they were there.

    Hi
    Thanks for your input.

    I do appreciate your opinion. But, I use my laptop out in the field, in a vehicle where it is awkward to use a mouse. So, the up / down arrows are essential to me and quite a few others who are also asking the question. Also, the up / down keys do not work on all websites.

    Can you advise the best way to roll back to FF45?

    Regards

    Laptop touchpads usually have a finger action for scrolling. Try 2-finger drag or 1-finger on the right side of the pad. Just a thought.

    Marvellous Jim..... That works a treat, better than the Scroll Buttons.

    Thanks
