Sir , in the FIREFOX browser app for Andriod there is no built in download manager , it is also not in add on store , this is a very important thing which you must give to us , in current version we are not able to pause and resume our downloads and to view with how much internet speed it's downloading , in countries like India we have very high data rates and also inconsistent and slow connections so when downloading a file which is pause and resume supported from the back-end side we are still not able to have pause and resume support in the Browser itself , firefox is a great browser but in this feature it gets beaten by the browsers like UC and it's not acceptable , i hope you improve this/
