I have just done a yum update for the first time in a while, and as part of that I believe Firefox got upgraded. After the reboot I restarted Firefox which had been closed down with the option to retain all open tabs/windows. However, when I restarted Firefox it had three new tabs, one being the ususal Firefox upgrade page. The other two were Phishing sites, one pretending to be Amazon the other I cannot remember. Has anyone else experienced this?
