Blowed if I can see how it happened or how to change it back - clicking web links in Mail opens things in Firefox, how do I make them open in Safari?
Anyone any thoughts please?
The default browser is set in Safari regardless of which browser you want to be the default. Go to Preferences and under the General tab, the top item sets it to any of the browsers you have - including Safari.
Some browsers (including Firefox I think) on downloading will offer to set itself as the default so changes the setting in Safari for you if you click yes.
