Website loading but just showing blank screen.
Sometimes when I try to load a new website, it appears to have finished loading, but there's just a blank screen. I first I thought it was just my internet being slow and the page just timing out, but then sometimes if I load a youtube video, the video the will start and the audio plays, without there being anything actually displayed on the screen. If I try to reload the page, it does nothing, but closing and reopening the page in a new tab does work.

Make sure you are not blocking content.
Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?
One issue that seems more common lately is Firefox's Tracking Protection feature. When it is blocking content in a page, a shield icon will appear at the left end of the address bar next to the padlock icon. This article has more info on managing this feature: Tracking Protection {web link}
