We have released a browser add-on that works with apps using NativeMessaging, but it stopped working after updating Firefox to v114 on Windows 10 (64bit). We have confirmed that it works up to v113.0.1. The browser add-on manifest is v2. In the Mac version using the same browser add-on, the application can be linked even after updating to v114. The behavior of the bug on Windows is similar to the behavior when NativeMessagingHosts is not written in the registry. Is there any information about solutions to problems or causes? Expected results: Launch app via NativeMessaging from browser addon User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64 rv:109.0) Gecko/20100101 Firefox/114.0
