Hi All, I want to block traffic on firefox externally for managed devices via Intune, following the import of the ADMX/ADML files into intune. Having read https://support.mozilla.org/en-US/kb/managing-firefox-intune I have set '\Mozilla\Firefox\Exceptions to blocked websites' to the following; //*.mydomain.com/* Which works, however, I also want to add hosts that are only resolving on IPs and not DNS. I can add specific IPs if known, but is there a way I can allow IP ranges? Ie //10.10.*/* (this doesn't currently work) Of the included screenshot, only the wildcard for mydomain.com and the specific IP currently work I've looked over the link that is recommened in the policy (indirectly) and can't see an option for allowing an IP range. https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/Match_patterns If there is a better way to do this via intune for firefox only, please let me know. Thanks
