My guess is their bot/scraper detection not liking anything that's not a 100% standard, extension-free browser. Although I've heard that even people without privacy extensions are getting hit by it, so it may just be a super aggressive bot detection that's randomly hitting everyone or some other bug that Twitter doesn't care because it presumably a) doesn't affect logged in users b) non-logged-in users who go there really want/need to see something (e.g. whether the US president is about to deport them) so they will put up with it and reload.
