Mozilla has emitted security updates for Firefox to address eight CVE-listed security flaws, five of them considered to be high-risk vulnerabilities.
The patches, present in Firefox 77, should be downloaded and installed automatically for most users, so if you haven't closed out and relaunched your browser in a while, now might be a good time.
Of the five high-risk flaws, three are confirmed to allow arbitrary code execution, which in the case of a web browser means that simply loading up a malicious page could lead to malware running on your machine. As it turns out, all three of the code execution bugs were found in-house by Mozilla developers, rather than miscreants exploiting them in the wild, which is good news.
