this is the second firefox update i have downloaded on my android tablets, and none of them work anymore, when you open firefox the tablets reboot after 5 seconds... I hate to say this but your latest version of firefox for android has caused me to switch to google chrome... I have been using firefox and its predecessor netscape since 1995... Why would you pass along an update version that does not work to people... I have 7 tablets in my household and all 7 are doing this...
