When I resize my window (smaller like mobile size) my vertical scrollbar vanishes if I go less than about 800px wide.

This was happening in version 9.0.1 and now in 10. I resize my window to test how my site looks in smaller screens (iTouch, iPad, etc.). Any suggestions? I don't have this problem in version 4.0.1 which I've been using up until this point.

That can happen if there are items on a toolbar that take a specific space.
You can try to hide the toolbars during the tests to see if that helps (View > Toolbars or Firefox > Options).

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

Thanks. Hiding the navigation bar did it for me.
