Need more? Here is a little more information about this issue and fix via Mozilla Developer News:

Due to the security fixes, we strongly recommend that all Firefox users upgrade to this latest release. If you are still running Firefox 1.5.0.x, you are highly encouraged to upgrade to the Firefox 2 series as Mozilla ceased supporting Firefox 1.5.0.x in May 2007. Simply choose “Check for Updates…” from the Help menu to begin the upgrade process.

For more information about the problem, check out this post on CyberNet News about it. Also if you want – you can download and install it via GetFirefox.com.

Here is the post that got my attention on UserScripts.org:

Someone has been attempting to post scripts that steal cookies. Thanks to several alert us.o citizens (including davey, descriptor, loucypher, joel h, pogue) we have been able to note that the script is malicious and then delete them.

I’m putting up a banner to warn people that newly uploaded/updated scripts should be put under extra scrutiny.

I’ve also decreased the cache duration of rss feeds to 10 minutes, so if you keep an eye on http://userscripts.org/feeds/recent_scripts it will be a lot fresher than normal (it was cached for an hour)

So yes, everybody should be extra careful when downloading scripts like this – even if it is from a trusted source. I am happy to see the UserScripts.org team moved so quickly on this though. That makes me feel a lot better about my continued use of their Firefox extension.
