User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:54.0) Gecko/20100101 Firefox/54.0 Build ID: 20170616092053 Steps to reproduce: I use firefox 56.0b2 64bit on windows 7 64 bit Every time I open firefox, it asks me if I would like to make firefox the default browser. Every time I say, yes, sure, "use firefox as my default browser". It is quite annoying. Can you please fix that, if somebody is still working on developing or at least fixing the firefox or is it finish? Thank you Actual results: Every time I open firefox, it asks me if I would like to make firefox the default browser. Expected results: Firefox should not ask me over and over again if I want to make it a default browser. It also does not work if I go to preferences -> general -> press the button "make default...". Nothing happens.
