Since yesterday clicking on a link in an email message firefox doesn't open a new tab with that particular website.
I am using Firefox 3.6.13 on a 2009 Mac Pro computer (OSX 10.6.6). Up until yesterday when I clicked on a link in an email message Firefox opened a new tab and switched to that particular website. Since yesterday Firefox doesn't do that. I have Firefox set up as my default browser. I tried to change my default browser to Safari, then everything worked fine. Clicking on a link in a message a new tab has opened in Safari with that particular website. My problem is, that I like Firefox a bit more than Safari and I'd like to know what to do to restore that functionality to Firefox.
