FireFox’s built in update checker happily notified me of the update as I browsing around today. 188.8.131.52 contains 1 critical security fix and 1 moderate security fix.
Fixed in Firefox 184.108.40.206
- MFSA 2007-27 Unescaped URIs passed to external programs
- MFSA 2007-26 Privilege escalation through chrome-loaded about:blank windows
That about sums up what was contained in the update. Considering one of the flaws that was fixed is rated as critical, I advise you to upgrade as soon as possible. You can download the latest version of FireFox by clicking here
