Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

You will need to restart Firefox for this to take effect so save all work first (e.g., mail you are composing, online documents you're editing, etc.,) and then perform these steps:

In Firefox 54 and below:

   Click the menu button and select Options (Windows) or Preferences (Mac, Linux).
   Select the Advanced panel and the General tab.
   Uncheck Use hardware acceleration when available.
   Close Firefox completely and then restart Firefox to see if the problem persists. 

In Firefox 55 and above:

   Click the menu button and select Options (Windows) or Preferences (Mac, Linux).
   Select the General panel.
   Under Performance, uncheck Use recommended performance settings. Additional settings will be displayed.

   Uncheck Use hardware acceleration when available.
   Close Firefox completely and then restart Firefox to see if the problem persists.

The above suggestions seem not appropriate for my Problem... as expressed in my Original Post/ Question. I have asked: Why we do not have Scroll bar Top and Bottom Buttons to aid in Scrolling using mouse pointer pressed? I have this facility in UBUNTU-Mate... not in other Ubuntu distributions

Hi Hariharan PV, Firefox usually tries to use the standard system controls. If the scrollbars in Firefox do not work the same way as other applications that use system controls, then there may be a bug. Are you testing with the build of Firefox you can download directly from Mozilla, or the builds in the respective repositories, which often have tweaks applied to them by the packagers?

I am using Latest FIREFOX 76.0.1-64 bit... If my problem can be supported... would be happy... and very thankful... regards

Does it make a difference if you use Firefox from the Mozilla server ?

What window manager do you use ? Is this a touch screen or touch pad device ?

I think the honorable members did not fully understand my problem... It is NOT THAT SCROLLING ISN't possible... but if we look at the Picture/ screenshot uploaded... we will note there are Two Nodes/ Buttons at top and bottom of Scrolling channel. These are not sen in UBUNTU, XUBUNTU, KUBUNTU, KDE NEON that I use. To me it ;looks like a basic Design problem at the MOZZILLA Design group... We need to call in their attention. I am using UBUNTU-Mate as my main OS... I have the said Nodes in this FIREFOX - not 9n others

Hi.. I have version 68.8 on Linux ORACLE 7.8

I quit firefox and restated now the scroll bar is BACK! ....

WHAT IS MISSING IS THE UP + DOWN ARROW IN THE SCROLL BAR ... LIKE CHROME HAS.

b24warbaby... yes. I dont have this problem in UBUNTU-Mate, in which FIREFOX does have the "UP" "DOWN buttons in the Scroll channel. I wish to have the same in other UBUNTU OS too... I am now using (apart from Mate) VOYAGER (which is UBUNTU Variant, with xfce Desktop, and also I have KUBUNTU... Both do not have the said "Scroll arrows" in FIREFOX.

My PROBLEM, still not solved :)

Some window managers on Linux only have have the scroll thumb and not the scroll bar buttons.

• /questions/1229675 No scroll button at both ends of scroll bar. Why?

It looks like... the said Problem is not being solved. I am unable to press the button :Solved the problem" as no appropriate suggestion/ answer could rectify the lacuna involved in FIREFOX... other than the UBUNTU-Mate based FOREFOX-browser

Did you try the gtk.css file ?

core-el... Thanks... I followed on your lead... One step took me to Qogir Theme... and I found something (probably) useful

The Direction: " Go to about:support in Firefox.

   Application Basics > Profile Directory > Open Directory." ... How do I do that? Where do I find "About"?  I am not such a Computer literate/ savvy as many here...  relatively a novice :)   I NEED additional support, to take me to the "about:support" in Firefox
