Menus Don't Show; Improper Page Scrolling
Sometimes when I start FF, it has the following problems:
- scrolling can only be accomplished by clicking-and-dragging the scrollbar; neither of page up/down, up/down keys, clicking the up/down buttons on the scrollbar, nor using the mousewheel do anything at all.
- tooltips, context menus, and GUI menus don't open; this includes the menu bar, toolbar, and right-click menu.
In the past, this used to happen just sometimes; in the past few days, no matter how many times I try opening FF, I consistently have this problem. Using Safe Mode hasn't affected the problem. Because menus don't display, I can't toggle hardware acceleration via menus; however, I've tried toggling layers.acceleration.disabled and general.smoothScroll -- both to no avail.
I'm using Linux 3.16.0-2-ARCH x86_64, Firefox 31.

Did you try to delete the Firefox program folder and reinstall Firefox? You can also try a new profile.
You can find the full version of the current Firefox 31.0 release in all languages and for all Operating Systems here:
Create a new profile as a test to check if your current profile is causing the problem.
See "Creating a profile":
- https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
- http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
It seems that toggling the layers.acceleration.disabled switch back to "false" in about:config solved everything. So in case anyone else has this problem, I'd try switching it from "false" to "true" and back a few times, restarting FF after each switch.
