Type about:config<enter> in the address bar. If a warning screen comes up, press the I Accept the Risk button. At the top of the screen is a search bar. Enter dom.disable_window From this list, set everything to True.

The Dom.disable_window settings takes away the websites ability to set up new windows in a way that takes away user controls. http://kb.mozillazine.org/Dom.disable_window_open_feature.status

I did exactly as you said and it still happened. Everything listed under dom.disable_window is still set to true, but my scroll bars still disappear.

Any other ideas?

Hello grstorga,

Would you please take a look at jscher2000's post (Chosen Solution) in this thread :

https://support.mozilla.org/en-US/questions/1132323

Would that work for you  ?

Thank you all for your replies, but I just went with an addon. It seems like there should be a way to lock scripts from disabling scrollbars, but all I can do is turn them back on.

Have a great weekend.

Would you be so kind as to share the name of that add-on with us  ? Might be helpful to others with the same problem  !

Thank you in advance (and have a great weekend)  !

I'm so sorry - I should have mentioned it. I went with Scroll Everywhere by Unai Valle. It appears to work fine.

Thanks again!

That was very good work. Well done. Please flag your last post as Solved Problem so others will know.
