Drop down menus and boxes not appearing
This problem just appeared this morning - no issues last evening.
In a website where I am a Mod, and required to vet postings, the discussion boxes and dropdown (on hover) menus are not appearing.
In addition, if I have multiple tabs in a single window, I can only access the right-most. To open the other tabs, I must close any tab to the right.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the Safe mode start window to disable all extensions.
You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
