As I am no native engish speaker, I appologize for my english.
I am building an Dashboard using the flexdashboard-package and highcharter to create nice graphs. Further, want to use a custom font: myfont.otf. When I run my code on my decive everything looks fine. But when I deploy it to shinyapps and open the page in Firefox, the font is not displayed correctly in my highcharts graphics. Strangely, when I use chrome to open the Page everything looks as desired. It is crutial to me that my dashboard looks the same regardeless which browser is used. Any help is appreciated.
