Thanks jdebunt, I wanted to read that. As far as I know coinyoo is legit, but I hold more trust in malware bytes than some weird btc site. Actually, a btc news site would be ideal for infecting computers with btc stealing malware. Coinyoo goes on my list of "banned" sites.
Anyways, the article is essentially click bait. Very thin on news very little info. Firefox has vulnerabilities (no news there) Firefox devs are working to fix said vulnerabilities (gosh)
Ironic how someone is using this to spread malware. Makes sense actually. Wham bam flim flam!
