I use ‘Firefox Developer Edition’ (blue icon) but as I am using it, it constantly switches to the ‘Firefox’ orange icon, as above.
I don’t know what triggers it and the switch is seamless - i.e. I don’t notice it happening while using it.
System monitor shows that ‘Firefox Developer Edition’ is running.
Default application = ‘Firefox Developer Edition’ for web + PDF.
I’ve spent hours on this but no solution. Help!!
