I'm running the Firefox web browser without plugins, but I know many Internet users who are running ten or even more plugins at all times in the browser. Activities like watching videos on YouTube require plugins, as Firefox is not yet supporting the H.264 format which is required to play back the videos not available in WebM format on the site.
My two main concerns with plugins are stability and security. Security updates are released regularly for plugins such as Adobe Flash Player or Java but it is still up to the user to install those updates the moment they come out. That, and the fact that companies like Adobe have failed to produce a working update system that does so are the main reason why many Internet users are running outdated and often insecure plugins in their web browser. This can be partially mitigated by installing a security add-on like NoScript in the browser which blocks automatic plugin execution on all websites you visit.
Stability is the other concern. Plugins may become unresponsive which sometimes requires you to restart the browser to continue working. In any event, you may wait a preset amount of time, currently set to 45 seconds, before Firefox kills the non-responding plugin so that you can keep on working with the browser.
Firefox's new Plugin Hang protection feature displays information about what is happening in the background to you to give you control over the next step.
It provides you with the option to stop the plugin right at that point in time, or wait and see if the plugin recovers. What's interesting here is that you are also informed which plugin caused the issue in the browser. Stopping the plugin will kill it but won't affect the underlying browser, provided that out of process plugins are used.
The feature is currently only planned for desktop versions of Firefox on Windows. You will note that a child process is created, plugin-hang-ui.exe which is used to display the dialog box to you when plugins hang in the web browser.
Several preferences are available that help you customize the feature:
The release target for the Plugin Hang UI is Firefox 19 which will come out on 19.2.2013 if everything goes according to plan. (via Techdows)
