Typical government website, first it says 'to use the e-services we recommend Internet Explorer as browser.' Directly followed by 'at the moment it is impossible to use certain e-services with Internet Explorer 11.'
To be honest, I don't use a lot of internet services. As a student without any income or taxes to file, well, I have little need for them. This came from a website run by the Swedish Transport Agency where I need to request my learner's permit from.
