It is often blocking the false positives.
So if developer has named one of their assets file with social media names like "twitter/facebook/etc", it blocks the file right away. Since it does not have custom configuration options for each site, you can either disable µBlock or go with the crashed site.
Not all the sites are written professionally by experts, and this becomes an issue when you are trying to purchase stuff from small online shops. (to support local sellers)
I am too busy for a pull request these days, but maybe this will be fixed soon by someone else. My point for µBlock is for now 5/10.
