Agree with @Falco – it’s likely one of the disabled/non-default/changed settings in your browser’s configuration. But without knowing what was disabled it would be difficult to know what might be causing the conflict. If it was a list of things you changed manually, you might try to look back at that list and revert the changes one-by-one and see if you can get the site working normally again.
