My browser has been having issues where it will show a black box out of a sudden. Or when i switch tabs, the previous tab will appear in the new tab (in a certain area). It's only temporary rectified when i close the whole browser and restart. Any idea how to rectify the issue?

Eg. First image was supposed to be on FB but it shows a different logo.

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

You can try to disable hardware acceleration in Firefox.

Close (Firefox -> Quit) and restart Firefox after modifying the setting for changes to take effect.
