Drop-down & Context menus appear at margins
I am running FireFox V59.0 on Ubuntu 16.04 and when I right-click on pages in a website (ie, to open a link in a new tab, to copy a string, etc.), the context menu appears at the display margin (edge) and not at the cursor position. Sometimes, on the same web page, the context menu will appear at the cursor position, and later during the same session, it will appear at the display margins (edges).
This behavior also happens on pull-down menus. When I click on the arrow to display my choices, the list appears at the screen margin and NOT below the field on the web page.
These odd behaviors happen on all types of web pages - but usually not on Facebook.
I can not repeat this behavior in Google Chrome (V65) - context and pull-down menus appear at the cursor location.

Note: Any customization will revert back to default, you will also need to reinstall Extensions.
Please let us know if this solved your issue or if need further assistance.
This issue of misplaced lists is a bit familiar.
When you say pull-down menus, do you mean select controls, a form control with a drop-down list?
A couple of Mac users with multiple displays of different resolutions linked the issue with using a DVI port (no issue with HDMI), but I have no idea whether that could be relevant to a Linux user.
