is this happening in vanadium? you don't mention which browser but i am assuming so. i wasn't able to reproduce this issue on either site mentioned, it may have to do with your configuration. are you using a dns, vpn, or similar service that could effect it?
as far as other browsers, i think its always good to have an alternate. mull is recommended around here a lot. i personally use duck duck go as my backup and standard firefox in a tertiary role.
