You can stop the plugin now, or you can continue to see if the plugin will complete". This article describes the reasons for this error message and covers possible solutions and workarounds. :[[Image:Firefox Plugin Hang UI]] __TOC__ = What to do = This error is telling you that Firefox thinks that a plugin may be running out of control and would make Firefox hang if nothing is done. The purpose of the Plugin Hang UI is twofold: * To inform the user which plugin is responsible for the hang and * Provide the user with an opportunity to terminate the plugin sooner than the default behavior. When the Plugin Hang UI appears, you have some options, as you can see above. == Select to Continue == If you think that a plugin will finally complete, then you can select {button Continue}. This way, you give a plugin more time to complete, although this may not always be succesful. Since the Plugin Hang UI has appeared, Firefox has suspended the plugin's execution. By selecting {button Continue} you let the plugin resume execution, and so it may finally complete. == Select to Stop the plugin == If you find that pressing {button Continue} brings up the same dialog again, then probably you should stop the plugin. You can do this by selecting {button Stop plugin}. = Prevent plugins from hanging = If you see that prompt often, you may have: * oudated plugins. [[T:plugincheck]] * several instance of the plugin running at the same time. Try to pause or stop the plugin in other tabs.

If you check "Don't ask me again", then Firefox will not show this warning again and will behave as in earlier versions, that is it hangs and makes the plugin crash after 45 seconds. If you want to see it again after disabling it, do the following: # [[T:aboutconfig]] # In the about:config page, search for the preference {pref dom.ipc.plugins.hangUITimeoutSecs}. # {for win,linux}Right-click{/for}{for mac}Hold down the {key Ctrl} key while you click{/for} on it and choose {menu Reset}.
