Firefox has an issue with the scroll bar on certain websites which makes it befin flashing and creeping towards the top of the page on some websites (See attached gif). This is particularly an issue on whilst logged into my university study portal.

I have already troubleshooted this by: - Disabling add-on's - Deactivating smooth scrolling - Deactivating auto-scrolling - Deactivating enhanced tracking protection. Nothing has resolved the issue.

Does it still happen in a new profile? An easy way to test a new profile is to install Developer Edition and see if it happens there or refresh your existing profile. Make sure you stay signed out of your sync account when testing.

You can create a new profile as a quick test to see if your current profile is causing the problem.

See "Creating a profile":

If the new profile works, you can transfer files from a previously used profile to the new profile, but be careful not to copy corrupted files to avoid carrying over problems.
