Open the Firefox > Web Developer > Scratchpad (Shift+F4) and paste this code in it and use Execute > Run (Ctrl+R) or create a bookmarklet with this code as the location.

javascript:void(document.body.style.setProperty('overflow-y','hidden','important'));void(document.body.style.setProperty('overflow-x','hidden','important'));

Change hidden to auto to get the scroll bar(s) back.

I assume that your post in [/questions/906990#answer-291125] ended up in the wrong thread and should have appeared here.

The only thing that changes if you run the code in the Scratchpad is the disappearance and reappearance of the scroll bar in the current tab. You do not see anything in the Scratchpad. So you need to switch back to the browser window. You can test it with this code, that should make both scroll bars appear:

void(document.body.style.setProperty("overflow","scroll",""));

[/questions/906990#answer-291125]:

In Scratchpad I ran both: .

void(document.body.style.setProperty("overflow-x","hidden",""));
.
and
.
void(document.body.style.setProperty("overflow-x","hidden",""));

In the 2nd one I got:

17:48:57.826 |x unexpected end of XML source
 @ Scratchpad:1'''
.
.
For the 1st one I got no activity, only a blinking cursor.
.
any other ideas ?
.
Good luck and merry Christmas,  Bill

Re: Scroll Bars

OK, I think that I've finally got it! One last question - In:

void(document.body.style.setProperty("overflow","scroll",""));

what do I change to HIDE BOTH the scroll bars ?

This code will hide both scroll bars:

void(document.body.style.setProperty("overflow","hidden",""));
