Menu and other menubar items don't have drop-down window

Hello, I am having an issue in which the menu and other toolbar items (library, etc) don't have a drop down menu or any kind of context. Clicking on them makes nothing happen. I can access the menu with about:preferences and so forth but this is really annoying and even within the menu I can't select from a multiple option drop down (usually used when selecting between three or more options). I am using linux mint kde, everything is updated. I have already tried both safe mode and refresh. Thanks Zach
