Firefox users always concerned about Firefox because its not stable and crashes too often.Mozilla identified outdated third party plugins pose security risk and also can crash Firefox down.Mozilla started to warn Firefox users to update their Flash player plug-in through update notification.

Mozilla started Plugin check service which shows Plug-in update status and from Firefox 3.6 onwards Firefox automatically alerts users if their plugins are out-of-date.Other browsers users can also check their plugins status with Plugin Check .

There are still problems with Firefox due to plugins like Adobe Flash Player, which causes entire browser session to crash when a plug-in on a Webpage becomes unresponsive or hangs.
