1300306 - Add back clickable up/down arrows to the scroll bar or add new "focus" button

Status: RESOLVED INVALID

(Firefox :: Untriaged, defect)

Description

[Greg]

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.89 Safari/537.36

Steps to reproduce:

Mozilla removed a much used feature of Firefox: the clickable up/down arrows on the scrollbar.


Actual results:

The scrollbar that appears on the right hand side of the screen no longer has clickable arrows at the top & bottom of the scrollbar. This makes it difficult to navigate web pages. I am forced to use the SpaceBar or PgUp/PgDn keys or Arrow Keys. Which I'm fine with EXCEPT these keys often don't work because they don't have focus. I land on a page and tap one of these keys and nothing happens (the mouse focus is somewhere else on the page). So I have to click somewhere on the page to bring the focus to it. Well, sometimes where I click turns out not to be "free" OR there isn't somewhere "free" to click and I get taken somewhere else and it is a major PITA not having clickable arrows on the scrollbar.

Further, if I click on the scrollbar in a section of it's open space, expecting the page to lower by one page length, I'm taken WAY down the page and forced to scroll way back up. The only way to use the scrollbar now is to click-it and hold while dragging, which is a PITA and not a very precise way to get around a webpage as I often need to advance an entire page or just a few segments to completely see something that is partially obstructed. So the scrollbar as it exists now has absolutely no function for real world use. Instead of being able to just bury the cursor in the corner of the screen and click to get page advancements, I have to completely change my focus, line up the cursor over the scrollbar and carefully navigate down a little bit to clear obstructions. Very poor ease of use.


Expected results:

In my thinking you should do one of two things:
1) add back clickable up/down arrows on the scrollbar
AND/OR
2) add a keyboard button (maybe an F-key) that if it is tapped, it will ALWAYS do just one thing: immediately move the focus to the page so that the PgUp/PgDn and Arrow Key keys always work to advance the page.

THis is not a Firefox bug. 
Because Firefox is using GTK3 now. And GTK3 removed scroll buttons on the scroll bar by default.

If you want to change the default behavior, try the following step.

1. Add the following to the file ~/.config/gtk-3.0/gtk.css
(create the file if it doesn't exist):

.scrollbar {
    -GtkScrollbar-has-backward-stepper: 1;
    -GtkScrollbar-has-forward-stepper: 1;
}

2. Restart Firefox if any

This overrides the default GTK3 style, causing scrollbars to have scrollbar buttons.
