How to by-pass "Get Newer Browser" nag messages?

I can't see simple pages from 'old browsers' (old increasingly meaning 'yesterday' lol)

For example
https://mail.disroot.org/?/BadBrowser
by disroot @disroot

SIDE NOTE:
I think #Wordpress Admins can avoid this message for users coming to it's site by installing this plugin (and maybe there is an add-on to by-pass it in a similar way)

https://wordpress.org/plugins/no-browser-nag/

(BUT might not be needed who knows until this nag screen comes up).... so if you surf the website http://freeschool.0id.org/ and get this 'bad browser' or 'no entry' message on my site let me know!

It's a unhand way of making people upgrade browser for very limited difference

Blocking me out 100% - oh well disroot can't even see landing page.

Disroot has disrooted it's older users and that's only to log into it's webmail - DOH!
