Well it is official Firefox just released version 18.104.22.168 which makes the old version 22.214.171.124 just 13 days old and not needed anymore. The following issues were fixed:
- MFSA 2007-27 Unescaped URIs passed to external programs
- MFSA 2007-26 Privilege escalation through chrome-loaded about:blank windows
This brings up the real question which is more annoying Windows Update (the passive update process) or Firefox update (the active update process). Honestly I prefer to stay ignorant about browser updates, because honestly I don't really care about unescaped uris. Not because I don't think they are a threat, but because I know the signs of a potential site that could cause harm and just avoid them.
