You can try to disable hardware acceleration in Firefox.

• Firefox > Preferences > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.

Unfortunately that didn't solve the issue. Hardware acceleration is off and my drivers are all up to date. This is an issue that only happens in firefox. No other browser or program has this problem.

The text in the context menu looks larger to me then the text in the background.

Do you know what is causing the increased font size?

Does this only happen in the right-click context menu or also in other places in the user interface?

As far as I can tell it is the same size. I don't have the text size changed manually anywhere and I have reset the zoom of the browser in case of accidental zooming.

The text on facebook does this too but not as bad, just a small bit of the top line is cut off. But the text input boxes on facebook all do it when I am typing a reply or a new status.

You can check for corrupted and duplicate fonts and other font issues:

Thank you! It does appear to have been a font issue. The issue has been resolved now.
