Even if you don’t use Firefox, here is an excellent reason to support the work that Mozilla is doing. Posted in their security blog along with a refresher on the plugin checker that added some time ago is news of some new development that seeks to expand that security coverage to all users, regardless of their browser choice.
We believe that plugin safety is an issue for the web as a whole, so while our initial efforts focused on building a page that would work for Firefox users, the team has since expanded plugin check coverage to work with Safari 4, Chrome 4, and Opera 10.5. We have added support for Internet Explorer 7 and 8 for the most popular plugins, as well, but since IE requires specific code to be written for each plugin it will take us a little longer to get to full coverage. You can see the updated page for yourself here.
Mozilla, as I’ve written about repeatedly, is also one of the browser makers working on better process compartmentalization to contain the risk of misbehaving plugins. Together, these two features offer a nice one-two punch to plugins as a source of security concerns and stability issues.
