Mozilla on Wednesday released an update to resolve six vulnerabilities, two rated as critical, in its Firefox web browser.
Version 126.96.36.199 staves off the possibility of spoofing, cross-site scripting and malicious code installation that could result from exploitation.
Storm Center handler Raul Siles wrote on the group's blog that users should consider running the open-source NoScript extension, offered by InformAction, to protect against attacks.
The other critical bug that was patched relates to a memory corruption error.
Mozilla also released version 1.1.9 of internet suite SeaMonkey and version 188.8.131.52 of email client Thunderbird.
