A web app says it doesn't support my browser.
First make sure, that the web app works in Firefox. If not, then there is sadly nothing I can do. Complain to the developers of the web app, though.
If it works in Firefox, make sure you followed the instruction in the "Permissions" section of the Installation manual.
