I don't want Brave as my default browser. Instead, Firefox (FF) is my default.
I have been using FF for many years, ever since it was called "Phoenix." Over the years, I have always been an ardent supporter of Mozilla, through donations as well as (sometimes) providing input concerning issues that needed fixing.
Therefore I am sticking with FF, with Opera (another long-time outfit) as my back-up.
Sad to say, Zorin is acting a bit like Microsoft in that, even though I have set Firefox as my default browser, Firefox needs to ask for default designation almost every time I use it after doing a startup or restart.
QUESTION: Is anyone having the same default issue as me? If so, I can live with it. If not, what might I be doing wrong?
I don't use either. I specifically installed 17.2 Core to avoid getting Brave, removed Firefox and use the App Image of Zen a fork of Firefox. But Zorin is only on for helping out here. My first choice is PCLOS Debian KDE Plasma, and second choice rolling release of Q4OS.
I think this will depend on how you've installed Firefox, but you should be able to select the default browser through Settings → Default Applications.
I've marked the reply above as the solution for the thread, although I should point out that @Dexxa reply was also pretty helpful to me, a it clarifies that the installation method doesn't seem to matter in this case.
