If you are a Firefox user and missed the update released yesterday, Adobe has patched three security flaws that specifically targeted the Mozilla Firefox browser.Adobe patched three new security flaw... Adobe Patches Flash Bugs, Attackers Targeted Firefox Users
For my main browser I have all plugins, such as Java, Flash, Shockwave etc disabled. If I do run across anything that needs flash I just download it (like say a video or game) or open it in a secondary browser. For those that have a hard time keeping up with all the updates while maintaining their sanity: https://browsercheck.qualys.com/
Well this one works, been stuck on 11.4.402.265, as the update after that wouldn't work, couldn't use the net as it just kept hanging.
I find this compliments Noscript on Firefox for plugin security: https://blog.mozilla.org/security/2012/10/11/click-to-play-plugins-blocklist-style/
this update to flash seems to of fix the whole issue of FF freezing a few seconds when loading heavy websites, with lots of things being loaded. Which in turn would freeze everything else like games in windowed fullscreen while FF was frozen for those few seconds. Atlest I have yet to see it happen this update.
