I have followed various instructions I found (such as stopping all add-ons etc, starting firefox in safe mode etc etc), but still no joy. When I click on a link in an email (outlook although not relevant I dont think), Firefox opens a new instance, starts in first tab with my default home page and then .... nothing. If I copy the selected hyperlink and put it in the search bar it works fine. More importantly, if I change *all* my defaults to say Chrome and try, it works fine. Any suggestions on what I am missing from the various solutions? (Been happening for ages - maybe a year or more I think).
