User Story
As a PRTG User, I want a way to not be prompted about an 'outdated' browser.
Details of User Story
It can be displayed for browsers that are not mainstream but work well enough for the user (Palemoon in my case), so this prompt is (mildly) troublesome and distracting since one may not want to use Chrome and the Web is supposed to be user driven. Well, I realize that is a very fringe interest; a good interface is supposed to include with every warning a way to dismiss it interactively but in this case a registry hack would be quite enough.
Acceptance criteria
Ideally a reply such as 'as of PRTG version xx.xx setting such registry key will prevent this prompt to be displayed.
Status
Denied as of 15.11.2018
Answering my own question I got rid of the annoying advertisement for Google by using the 'unsupported and deprecated feature' of editing styles_custom_v2.css to add the following, force refresh PRTG afterwards:
.browsercheck { display: none };
