How to Enable Slow Startup Notification in Mozilla Firefox

Mozilla Firefox has a very nice feature built inside that can tell you if your installed copy of Firefox browser is taking too much time to start. This unwanted delay in browser startup could be due to some of the plugins or extensions that you have installed in the Firefox. When Firefox determines that it is taking too long to startup, it will show a notification near the bottom of the window telling you that – “Mozilla Firefox seems… slow… to start”. And you have two options – you can either choose to learn about why the browser might be slow and how you can speed it up, or you can disable the notification from being shown up in the future.

If you choose to disable this notification then it will never show again. This could prevent you from taking the benefit of the helpful suggestions shown by Firefox and make your browser perform better if you decide to follow these helpful tips.
