Firefox keeps updating
Start Firefox and click on the Tools menu and then select the Options menu item.When the Options dialog opens, click on the Advanced category and then select the Update tab.By disabling the silent updates Firefox will still be able to update itself, but you will now be prompted with a UAC dialog so that you are aware that an update is occurring.You can disable silent updates using two methods, which are described below.In the Firefox updates: section, select Check for updates, but let me choose whether to install them.Then uncheck the checkbox labeled Use a background service to install updates.The browser developers generally avoid the use of the Flash plug-in because of the possibility of the sudden browser crash.An outdated or old Flash plug-in version can as well freeze the functioning of the application.
If you do not install the updates, you could put your computer at significant risk due to potential security vulnerabilities that these updates may be fixing.
So, this is how to verify if your device system is updated to its recent release or not.
Firefox application mainly supports the Flash plug-in platform.
