Hi I am sorry, but I do not understand your question. How can we help you with Firefox for Android?

The System Details list shows a Firefox 46 version: *User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:46.0) Gecko/20100101 Firefox/46.0 The current requirements for Whatsapp seem to be Windows 8 or higher or Mac OS X 10.10 or higher and Firefox 60 or higher, no mention of supporting Linux. If your OS is supported then you need to update a more recent Firefox version, otherwise you need to update to a newer Windows version or you can consider to switch to a Linux distribution that supports your hardware. *https://www.whatsapp.com/download *https://web.whatsapp.com/ See also: *https://support.mozilla.org/en-US/kb/how-reset-default-user-agent-firefox *https://support.mozilla.org/en-US/kb/Finding+your+Firefox+version
